Answer 9

Simplifying
4(3 + 7) = 4x + 4 * 7

Combine like terms: 3 + 7 = 10
4(10) = 4x + 4 * 7

Multiply 4 * 10
40 = 4x + 4 * 7

Multiply 4 * 7
40 = 4x + 28

Reorder the terms:
40 = 28 + 4x

Solving
40 = 28 + 4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4x' to each side of the equation.
40 + -4x = 28 + 4x + -4x

Combine like terms: 4x + -4x = 0
40 + -4x = 28 + 0
40 + -4x = 28

Add '-40' to each side of the equation.
40 + -40 + -4x = 28 + -40

Combine like terms: 40 + -40 = 0
0 + -4x = 28 + -40
-4x = 28 + -40

Combine like terms: 28 + -40 = -12
-4x = -12

Divide each side by '-4'.
x = 3

Simplifying
x = 3
