Question

Help pls I don't know what to do

Answer 1

Answer B, (-2,-4)

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.
