8.5x + 55 = 123

You would use the formula: mx + b = y

The solution to the inequality expression is x ≥ 30

<h3>How to solve the inequality expression?</h3>

The inequality expression is given as:

8x - 3(2x - 4) ≤ 3(x - 6)

Open the brackets in the above inequality expression

8x - 6x + 12 ≤ 3x - 18

Collect the like terms in the above inequality expression

8x - 6x - 3x ≤ -12 - 18

Evaluate the like terms in the above inequality expression

-x ≤ -30

Divide both sides of the above inequality expression by -1

x ≥ 30

Hence, the solution to the inequality expression is x ≥ 30
