1.) Which equation will result if the substitution method is used to solve the following system of linear equations?

x+y=6

x=y+2

x+y=y+2

x + (y+2) = 6

x = (x-6) + 2

(y+2) + y=6

2.) Solve the following system of equations by linear combination:

5x+2y=14

y=x-7

(-3,4)

(2,-5)

(4,-3)

(-5,2)
