question
solve the system by substitution.
( y = 4x + 22 )
( y = -7x )
answer
attempt 1 out of 2

Explanation:

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

$-7x = 4x + 22$

Step2: Isolate $x$ terms on one side

$-7x - 4x = 22$
$\implies -11x = 22$

Step3: Solve for $x$

$x = \frac{22}{-11} = -2$

Step4: Substitute $x=-2$ into $y=-7x$

$y = -7\times(-2) = 14$

Answer:

$x=-2$, $y=14$
