Question

1. y = -2

4x - 3y = 18

Explanation:

Step1: Substitute $y=-2$ into the equation

Substitute $y=-2$ into $4x - 3y = 18$:
$4x - 3(-2) = 18$

Step2: Simplify the constant term

Calculate the product of $-3$ and $-2$:
$4x + 6 = 18$

Step3: Isolate the $x$-term

Subtract 6 from both sides:
$4x = 18 - 6$
$4x = 12$

Step4: Solve for $x$

Divide both sides by 4:
$x = \frac{12}{4}$
$x = 3$

Answer:

$x=3$, $y=-2$
