Question

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

Explanation:

Step1: Substitute y from first equation

Since $y = 9x$, replace $y$ in the second equation:
$9x = 3x - 24$

Step2: Isolate x terms

Subtract $3x$ from both sides:
$9x - 3x = -24$
$6x = -24$

Step3: Solve for x

Divide both sides by 6:
$x = \frac{-24}{6} = -4$

Step4: Solve for y

Substitute $x=-4$ into $y=9x$:
$y = 9\times(-4) = -36$

Answer:

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