Answer 1

A,(‒6,1)

Explanation:

y=7x+43

y=2x+13

(choose one equation &multiply by ‒1 to be y=0)

‒y=‒7x‒43

y=2x+13

0=‒5x‒30

we got the equation this (‒5x‒30=0) now we can solve x

‒5x‒30=0

‒5x=30

‒5x/‒5=30/‒5

x=‒6 (now we got the value of x, then we will find tge value of y by substitute )

y=2x+13

y=2(‒6)+13

y=‒12+13

y=1

therefore the pairs will be (‒6,1)

i hope my answer is clear
