Step-by-step explanation:
Simplifying
(14x + 70) = (20x + 8)
Reorder the terms:
(70 + 14x) = (20x + 8)
Remove parenthesis around (70 + 14x)
70 + 14x = (20x + 8)
Reorder the terms:
70 + 14x = (8 + 20x)
Remove parenthesis around (8 + 20x)
70 + 14x = 8 + 20x
Solving
70 + 14x = 8 + 20x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-20x' to each side of the equation.
70 + 14x + - 20x = 8 + 20x + - 20x
Combine like terms: 14x + - 20x = - 6x
70 + - 6x = 8 + 20x + - 20x
Combine like terms: 20x + - 20x = 0
70 + - 6x = 8 + 0
70 + - 6x = 8
Add '-70' to each side of the equation.
70 + - 70 + - 6x = 8 + - 70
Combine like terms: 70 + - 70 = 0
0 + - 6x = 8 + - 70
-6x = 8 + - 70
Combine like terms: 8 + - 70 = - 62
-6x = - 62
Divide each side by '-6'.
x = 10.33333333
Simplifying
x = 10.33333333
