Answer:
(-2,-2)
Step-by-step 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)
