Question

solve the system by substitution.
y = 9x
y = 3x - 24
answer
attempt 1 out of 2

Explanation:

Step1: Substitute $y=9x$ into second equation

$9x = 3x - 24$

Step2: Isolate $x$ terms

$9x - 3x = -24$
$6x = -24$

Step3: Solve for $x$

$x = \frac{-24}{6} = -4$

Step4: Substitute $x=-4$ into $y=9x$

$y = 9\times(-4)$

Answer:

$x=-4$, $y=-36$
