Answer 1

5x + 8(2x + -9) = 54

Reorder the terms:

5x + 8(-9 + 2x) = 54

5x + (-9 * 8 + 2x * 8) = 54

5x + (-72 + 16x) = 54

Reorder the terms:

-72 + 5x + 16x = 54

Combine like terms: 5x + 16x = 21x

-72 + 21x = 54

Solving

-72 + 21x = 54

Solving for variable 'x'.

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

Add '72' to each side of the equation.

-72 + 72 + 21x = 54 + 72

Combine like terms: -72 + 72 = 0

0 + 21x = 54 + 72

21x = 54 + 72

Combine like terms: 54 + 72 = 126

21x = 126

Divide each side by '21'.

x = 6

Simplifying

x = 6
