Kali Bryant · Answer 1

c.) x = 3

Step-by-step explanation:

2x - 3y = 9

x = 4 + y

Substitute the second equation into the first equation

2 (4+y) - 3y = 9

Distribute

8+2y - 3y = 9

8-y = 9

Subtract 8 from each side

8-y-8 = 9-8

-y = 1

Multiply by - 1

y = -1

Now solve for x

x = 4-1

x = 3
