Y = 1/2x + 2
y = -3x + 9

1. x=2y-4

2. x=−1/3y+3

Step-by-step explanation:

1.

Let's solve for x:

y=1/2x+2

Step 1: Flip the equation

1/2x+2=y

Step 2: Add -2 to both sides

1/2x+2+−2=y+−2

1/2x=y−2

Step 3: Divide both sides by 1/2

1/2x/1/2=y−2/1/2

x=2y−4

x=2y−4

2.

Let's solve for x:

y=−3x+9

Step 1: Flip the equation

−3x+9=y

Step 2: Add -9 to both sides

−3x+9+−9=y+−9

−3x=y−9

Step 3: Divide both sides by -3

−3x/−3

=y−9/−3

x=−1/3y+3

x=−1/3y+3
