Answer:
Simplifying
8x + -3 = 5(2x + 1)
Reorder the terms:
-3 + 8x = 5(2x + 1)
Reorder the terms:
-3 + 8x = 5(1 + 2x)
-3 + 8x = (1 * 5 + 2x * 5)
-3 + 8x = (5 + 10x)
Solving
-3 + 8x = 5 + 10x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-10x' to each side of the equation.
-3 + 8x + -10x = 5 + 10x + -10x
Combine like terms: 8x + -10x = -2x
-3 + -2x = 5 + 10x + -10x
Combine like terms: 10x + -10x = 0
-3 + -2x = 5 + 0
-3 + -2x = 5
Add '3' to each side of the equation.
-3 + 3 + -2x = 5 + 3
Combine like terms: -3 + 3 = 0
0 + -2x = 5 + 3
-2x = 5 + 3
Combine like terms: 5 + 3 = 8
-2x = 8
Divide each side by '-2'.
x = -4
Simplifying
x = -4
