Question

solve the system by substitution.
$y = -x - 32$
$y = 7x$
answer attempt 1 out of 2
(\boxed{\space}, \boxed{\space})$ submit answer

Explanation:

Step1: Substitute $y=7x$ into first equation

$7x = -x - 32$

Step2: Isolate $x$ terms

$7x + x = -32$
$8x = -32$

Step3: Solve for $x$

$x = \frac{-32}{8} = -4$

Step4: Solve for $y$ using $y=7x$

$y = 7\times(-4) = -28$

Answer:

$(-4, -28)$
