Answer:
Simplifying
20x + -5 = 14x + 7
Reorder the terms:
-5 + 20x = 14x + 7
Reorder the terms:
-5 + 20x = 7 + 14x
Solving
-5 + 20x = 7 + 14x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-14x' to each side of the equation.
-5 + 20x + -14x = 7 + 14x + -14x
Combine like terms: 20x + -14x = 6x
-5 + 6x = 7 + 14x + -14x
Combine like terms: 14x + -14x = 0
-5 + 6x = 7 + 0
-5 + 6x = 7
Add '5' to each side of the equation.
-5 + 5 + 6x = 7 + 5
Combine like terms: -5 + 5 = 0
0 + 6x = 7 + 5
6x = 7 + 5
Combine like terms: 7 + 5 = 12
6x = 12
Divide each side by '6'.
x = 2
Simplifying
x = 2
