3x + 9y = -42 -3x + 2y = -2 the solution to the system is

Hi there,

The solution for y= -4 and for x it is -2. You can also write it as (-2,-4). If you need all the steps let me know. I can show you. Otherwise, Hope it helps.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

the answer is b.)
