What value makes the equation −5 = 4 − (3x/4−3x) undefined
The value that makes the equation undefined is when the denominator of the fraction becomes zero. In this case, the denominator is (3x/4 - 3x). To find the value that makes it zero, we can set the denominator equal to zero and solve for x:
3x/4 - 3x = 0
Multiplying both sides of the equation by 4 to eliminate the fraction:
3x - 12x = 0
-9x = 0
Dividing both sides by -9:
x = 0
Therefore, the value of x that makes the equation undefined is x = 0.
3x/4 - 3x = 0
Multiplying both sides of the equation by 4 to eliminate the fraction:
3x - 12x = 0
-9x = 0
Dividing both sides by -9:
x = 0
Therefore, the value of x that makes the equation undefined is x = 0.

4/3
−3/4
3/4
−4/3
4/3
−3/4
3/4
−4/3
The value that makes the equation undefined is -4/3.
To determine this, we need to find the value that causes the denominator of the fraction (3x/4 - 3x) to be equal to zero. To solve for x, we set the denominator to zero:
3x/4 - 3x = 0
To make it easier to solve, we can factor out a common term of x:
x * (3/4 - 3) = 0
Simplifying further:
3x/4 - 12x/4 = 0
-9x/4 = 0
Multiplying both sides by 4 to eliminate the fraction:
-9x = 0
Therefore, the solution is x = 0.
The equation does not become undefined when x = 0. To find the value that makes the equation undefined, we need to find the value that makes the denominator zero. However, in this case, no value of x makes the equation undefined.

To solve the equation (30/k) + 1 = 4 for the variable k, we can follow these steps:
1. Subtract 1 from both sides of the equation:
(30/k) = 3
2. Multiply both sides of the equation by k to eliminate the fraction:
(30/k) * k = 3 * k
30 = 3k
3. Divide both sides of the equation by 3 to isolate k:
30/3 = 3k/3
10 = k
Therefore, the solution for the variable k in the equation (30/k) + 1 = 4 is k = 10.
1. Subtract 1 from both sides of the equation:
(30/k) = 3
2. Multiply both sides of the equation by k to eliminate the fraction:
(30/k) * k = 3 * k
30 = 3k
3. Divide both sides of the equation by 3 to isolate k:
30/3 = 3k/3
10 = k
Therefore, the solution for the variable k in the equation (30/k) + 1 = 4 is k = 10.
What is the value for the variable f in (17/3f - 1) = 1?
To solve the equation (17/3f - 1) = 1 for the variable f, we can follow these steps:
1. Add 1 to both sides of the equation:
(17/3f - 1) + 1 = 1 + 1
17/3f = 2
2. Multiply both sides of the equation by 3f to eliminate the fraction:
(17/3f) * 3f = 2 * 3f
17 = 6f
3. Divide both sides of the equation by 6 to isolate f:
17/6 = 6f/6
17/6 = f
Therefore, the value for the variable f in the equation (17/3f - 1) = 1 is f = 17/6.
1. Add 1 to both sides of the equation:
(17/3f - 1) + 1 = 1 + 1
17/3f = 2
2. Multiply both sides of the equation by 3f to eliminate the fraction:
(17/3f) * 3f = 2 * 3f
17 = 6f
3. Divide both sides of the equation by 6 to isolate f:
17/6 = 6f/6
17/6 = f
Therefore, the value for the variable f in the equation (17/3f - 1) = 1 is f = 17/6.
