What is the first step for solving the system? x = 4 − 2 y x=4-2y x = 4 − 2 y 3 x − 2 y = 4 3x-2y=4 3 x − 2 y = 4

3 ( 4 − 2 y ) − 2 y = 4 3\left(4-2y\right)-2y=4 3 ( 4 − 2 y ) − 2 y = 4

3 x − 2 ( 4 − 2 y ) = 4 3x-2\left(4-2y\right)=4 3 x − 2 ( 4 − 2 y ) = 4

3 x ( 4 − 2 y ) − 2 y = 4 3x\left(4-2y\right)-2y=4 3 x ( 4 − 2 y ) − 2 y = 4

Solve the system? (Show work in your note packet 4-78 A) x = 4 − 2 y x=4-2y x = 4 − 2 y 3 x − 2 y = 4 3x-2y=4 3 x − 2 y = 4

What is the first step for solving the system? x = − 5 y + 2 x=-5y+2\ \ \ \ x = − 5 y + 2 x = 3 y − 2 x=3y-2 x = 3 y − 2

− 5 y + 2 = 3 y − 2 -5y+2=3y-2 − 5 y + 2 = 3 y − 2

− 5 ( 3 y − 2 ) = 3 ( − 5 y + 2 ) -5\left(3y-2\right)=3\left(-5y+2\right) − 5 ( 3 y − 2 ) = 3 ( − 5 y + 2 )

3 ( − 5 y − 2 ) + 3 y − 2 = 10 3\left(-5y-2\right)+3y-2=10 3 ( − 5 y − 2 ) + 3 y − 2 = 1 0

Solve the system? (Show work in your note packet A-78 C) x = − 5 y + 2 x=-5y+2\ \ \ \ x = − 5 y + 2 x = 3 y − 2 x=3y-2 x = 3 y − 2
