Answer 1

(-2,-2)

Explanation:

Step: Substitute 3x+4 for y in y=−x−4:

y=−x−4

3x+4=−x−4

3x+4+x=−x−4+x (Add x to both sides)

4x+4=−4

4x+4+−4=−4+−4 (Add -4 to both sides)

4x=−8

4x/4=−8/4(Divide both sides by 4)

x=−2

Step: Substitute −2 for x in y=3x+4:

y=3x+4

y=(3)(−2)+4

y=−2(Simplify both sides of the equation)
