3.) x + y = 12
4.) 4x + 2y = 32

x + y = 12.....x int = 12, y int = 12
4x + 2y = 32...x int = 8, y int = 16

texaschic101 · Answer

x + y = 12....x = 12 - y
4x + 2y = 32
4(12 - y) + 2y = 32
48 - 4y + 2y = 32
- 2y = - 16
y = 8

x + y = 12
x + 8 = 12
x = 4

it can be checked by subbing in ur answers into the original eq's to see if they equal
