Question

lve the system by substitution.
10x = y
2x + y = -24

Explanation:

Step1: Substitute $y=10x$ into second equation

$2x + 10x = -24$

Step2: Combine like terms

$12x = -24$

Step3: Solve for $x$

$x = \frac{-24}{12} = -2$

Step4: Substitute $x=-2$ into $y=10x$

$y = 10\times(-2) = -20$

Answer:

$x=-2$, $y=-20$
