Question

1. solve the equation $y = \frac{1}{2}x + 3$ for $x$ when $y = 8$.

Explanation:

Step1: Substitute y=8 into equation

$8 = \frac{1}{2}x + 3$

Step2: Subtract 3 from both sides

$8 - 3 = \frac{1}{2}x$
$5 = \frac{1}{2}x$

Step3: Multiply both sides by 2

$x = 5 \times 2$
$x = 10$

Answer:

10
