-4
Step-by-step explanation:
Simplifying
5 + 3x = 7 (x + 3)
Reorder the terms:
5 + 3x = 7 (3 + x)
5 + 3x = (3 * 7 + x * 7)
5 + 3x = (21 + 7x)
Solving
5 + 3x = 21 + 7x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7x' to each side of the equation.
5 + 3x + - 7x = 21 + 7x + - 7x
Combine like terms: 3x + - 7x = - 4x
5 + - 4x = 21 + 7x + - 7x
Combine like terms: 7x + - 7x = 0
5 + - 4x = 21 + 0
5 + - 4x = 21
Add '-5' to each side of the equation.
5 + - 5 + - 4x = 21 + - 5
Combine like terms: 5 + - 5 = 0
0 + - 4x = 21 + - 5
-4x = 21 + - 5
Combine like terms: 21 + - 5 = 16
-4x = 16
Divide each side by '-4'.
x = - 4
Simplifying
x = - 4
