Question

1
\frac{3(8x + 24)}{12} = 9 - 3(x - 4)
\frac{8x + 24}{4} = 9 - 3(x - 4)
2x + 6 = 9 - 3(x - 4)
2x + 6 = 9 - 3x + 12
2x + 6 = -3x + 21
\underline{+ 3x \qquad \qquad \quad + 3x}
\square = \square

Explanation:

Step1: Simplify left side

Left side after adding \(3x\): \(2x + 6+3x=5x + 6\)

Step2: Simplify right side

Right side after adding \(3x\): \(-3x + 21+3x = 21\)

Answer:

Left box: \(5x + 6\), Right box: \(21\)
