Question

1. solve for x. show your work

9x - 3x + 5 = x + 90

Explanation:

Step1: Combine like terms on left

$9x - 3x + 5 = 6x + 5$
So the equation becomes: $6x + 5 = x + 90$

Step2: Subtract $x$ from both sides

$6x - x + 5 = 90$
$5x + 5 = 90$

Step3: Subtract 5 from both sides

$5x = 90 - 5$
$5x = 85$

Step4: Divide by 5 on both sides

$x = \frac{85}{5}$

Answer:

$x = 17$
