Question

Y= -7x-7 y= 5x+5 substitution method

Answer 1

answer:

x=-1, y=0

step-by-step explanation:

y= -7x-7, y= 5x+5

substitute−7x−7for y=5x+5:

y=5x+5

−7x−7=5x+5

−7x−7+−5x=5x+5+−5x(add -5x to both sides)

−12x−7=5

−12x−7+7=5+7(add 7 to both sides)

−12x=12

-12x/-12=12/-12 (divide both sides by -12)

x=−1

substitute−1 for x in y=−7x−7:

y=−7x−7

y=(−7)(−1)−7

y=0(simplify both sides of the equation)

answer: x=−1 and y=0

good luck :)

hopefully, this helps

have a great day !!
