Solve for x
12 - x/9 = 11
x = __
x = 9
Solve for x
-20 = -5 + 3x
x = __
x = -5
Solve for x
20 = 5 - 3/8x
x = ___
To solve for x in the equation 20 = 5 - (3/8)x, we can start by isolating the x term on one side:

20 = 5 - (3/8)x
Subtract 5 from both sides:
20 - 5 = 5 - 5 - (3/8)x
15 = - (3/8)x
To solve for x, multiply both sides by -8/3:
15 * (-8/3) = - (3/8)x * (-8/3)
The left side simplifies to:
-40 = x

Therefore, the solution for x in the equation x = -40.
Solve for x 4(x + 7) -3(x - 5) = 44
To solve for x in the equation 4(x + 7) - 3(x - 5) = 44, we can first distribute the coefficients:

4(x + 7) - 3(x - 5) = 44
4x + 28 - 3x + 15 = 44

Combine like terms:
x + 43 = 44

Subtract 43 from both sides:
x = 1

Therefore, the solution for x in the equation is x = 1.
Solve for x -8x + 5(2x - 10) = -30
To solve for x in the equation -8x + 5(2x - 10) = -30, we first distribute the 5 on the right side, we get:

-8x + 10x - 50 = -30

Combine like terms:
2x - 50 = -30

Add 50 to both sides:
2x = 20

Divide by 2 on both sides:
x = 10

Therefore, the solution for x in the equation is x = 10.
