(7, 2)
solve.
10+x/3=1
7 (3x-4)=49
1.3+0.5x=-3.41
10+x/3=1
7 (3x-4)=49
1.3+0.5x=-3.41
To solve these equations, we will work through each one step by step:
1) 10 + x/3 = 1
To isolate the x-term, we can subtract 10 from both sides:
10 - 10 + x/3 = 1 - 10
x/3 = -9
To remove the fraction, we can multiply both sides by 3:
3 * (x/3) = -9 * 3
x = -27
Therefore, the solution to the equation is x = -27.
2) 7(3x - 4) = 49
We can distribute the 7 on the left side of the equation:
7 * 3x - 7 * 4 = 49
21x - 28 = 49
Next, we can add 28 to both sides to isolate the x-term:
21x - 28 + 28 = 49 + 28
21x = 77
To solve for x, we divide both sides by 21:
21x/21 = 77/21
x = 3.67
Therefore, the solution to the equation is x = 3.67.
3) 1.3 + 0.5x = -3.41
To isolate the x-term, we can subtract 1.3 from both sides:
1.3 - 1.3 + 0.5x = -3.41 - 1.3
0.5x = -4.71
Next, to solve for x, we divide both sides by 0.5:
0.5x/0.5 = -4.71/0.5
x = -9.42
Therefore, the solution to the equation is x = -9.42.
1) 10 + x/3 = 1
To isolate the x-term, we can subtract 10 from both sides:
10 - 10 + x/3 = 1 - 10
x/3 = -9
To remove the fraction, we can multiply both sides by 3:
3 * (x/3) = -9 * 3
x = -27
Therefore, the solution to the equation is x = -27.
2) 7(3x - 4) = 49
We can distribute the 7 on the left side of the equation:
7 * 3x - 7 * 4 = 49
21x - 28 = 49
Next, we can add 28 to both sides to isolate the x-term:
21x - 28 + 28 = 49 + 28
21x = 77
To solve for x, we divide both sides by 21:
21x/21 = 77/21
x = 3.67
Therefore, the solution to the equation is x = 3.67.
3) 1.3 + 0.5x = -3.41
To isolate the x-term, we can subtract 1.3 from both sides:
1.3 - 1.3 + 0.5x = -3.41 - 1.3
0.5x = -4.71
Next, to solve for x, we divide both sides by 0.5:
0.5x/0.5 = -4.71/0.5
x = -9.42
Therefore, the solution to the equation is x = -9.42.
