Question

What is the solution to the system of equations?

y = –3x – 2

5x + 2y = 15

(–40, 19)
(–19, 55)
(19, –40)
(55, –19)

Answer 1

(-19,55) x is equal to -19 and y is equal to 55

Answer 2

(–19, 55)
Replacing y in the second equation gives;
5x+2(-3x-2)=15
5x-6x-4=15
-x-4=15
-x=19
x=-19

y=-3(-19)-2
y=57-2
y=55

(-19, 55)
