Question

what is the value of x in the equation $1.5(x + 4) - 3 = 4.5(x - 2)$?
○ 3
○ 4
○ 5
○ 9

Explanation:

Step1: Expand both sides

$1.5x + 6 - 3 = 4.5x - 9$

Step2: Simplify constant terms

$1.5x + 3 = 4.5x - 9$

Step3: Isolate x terms

$3 + 9 = 4.5x - 1.5x$

Step4: Calculate both sides

$12 = 3x$

Step5: Solve for x

$x = \frac{12}{3}$
