Question

Solve the system by the substitution method. *8x – 3y = -22y = 5x + 19 (-5,6) (4,-3) (0,-5) (-3,4)

Answer 1

8x - 3y = -22

y = 5x + 19

Substituting the second equation into the first one:

8x - 3(5x + 19) = -22

8x - 3*5x - 3*19 = -22

8x - 15x - 57 = -22

-7x = -22 + 57

x = 35/(-7)

x =
