Explanation

Simplifying
\(5x + 32 = 4 + -2x\)

Reorder the terms:
\(32 + 5x = 4 + -2x\)

Solving
\(32 + 5x = 4 + -2x\)

Solving for variable 'x'.

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

Add '2x' to each side of the equation.
\(32 + 5x + 2x = 4 + -2x + 2x\)

Combine like terms: 5x + 2x = 7x
\(32 + 7x = 4 + -2x + 2x\)

Combine like terms: -2x + 2x = 0
\(32 + 7x = 4 + 0\)
\(32 + 7x = 4\)

Add '-32' to each side of the equation.
\(32 + -32 + 7x = 4 + -32\)

Combine like terms: \(32 + -32 = 0\)
\(0 + 7x = 4 + -32\)
\(7x = 4 + -32\)

Combine like terms: \(4 + -32 = -28\)
\(7x = -28\)

Divide each side by '7'.
\(x = -4\)

Simplifying
\(x = -4\)

Hence option A is correct.
