To solve for x, we need to isolate it on one side of the equation.
Multiply both sides of the equation by 8/3:
20 * (8/3) = -3/8x * (8/3)
Simplify the equation:
160/3 = -8x/3
Multiply both sides of the equation by 3:
(160/3) * 3 = (-8x/3) * 3
Simplify the equation:
160 = -8x
Divide both sides of the equation by -8:
160 / -8 = -8x / -8
Simplify the equation:
-20 = x
The solution is x = -20.

To solve for x, we need to isolate it on one side of the equation.
Start by distributing the 7 to the terms inside the parentheses:
28x - 105 = 63
Next, add 105 to both sides of the equation:
28x - 105 + 105 = 63 + 105
Simplify the equation:
28x = 168
To solve for x, divide both sides of the equation by 28:
(28x)/28 = 168/28
Simplify the equation:
x = 6
The solution is x = 6.
