Answer:
Answer B, (-2,-4)
Step-by-step explanation:
Let's solve your system by substitution.
y=3x+2;y=−2x−8
Step: Solvey=3x+2for y:
y=3x+2
Step: Substitute3x+2foryiny=−2x−8:
y=−2x−8
3x+2=−2x−8
3x+2+2x=−2x−8+2x(Add 2x to both sides)
5x+2=−8
5x+2+−2=−8+−2(Add -2 to both sides)
5x= −10
5 5
(Divide both sides by 5)
x=−2
Step: Substitute−2 for x in y=3x+2:
y=3x+2
y=(3)(−2)+2
y=−4(Simplify both sides of the equation)
Hope this helps good luck.
