Answer:5
Step-by-step explanation:
Simplifying
8x + -20 = 3x + 5
Reorder the terms:
-20 + 8x = 3x + 5
Reorder the terms:
-20 + 8x = 5 + 3x
Solving
-20 + 8x = 5 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-20 + 8x + -3x = 5 + 3x + -3x
Combine like terms: 8x + -3x = 5x
-20 + 5x = 5 + 3x + -3x
Combine like terms: 3x + -3x = 0
-20 + 5x = 5 + 0
-20 + 5x = 5
Add '20' to each side of the equation.
-20 + 20 + 5x = 5 + 20
Combine like terms: -20 + 20 = 0
0 + 5x = 5 + 20
5x = 5 + 20
Combine like terms: 5 + 20 = 25
5x = 25
Divide each side by '5'.
x = 5
Simplifying
x = 5
