Question

solve using substitution.
$y = 8x + 2$
$y = 5x - 1$
$\left(\square,\square\
ight)$

Explanation:

Step1: Substitute $y=8x+2$ into $y=5x-1$

$8x + 2 = 5x - 1$

Step2: Solve for $x$

$8x - 5x = -1 - 2$
$3x = -3$
$x = -1$

Step3: Find $y$ using $x=-1$

$y = 8(-1) + 2 = -8 + 2 = -6$

Answer:

$(-1, -6)$
