Answer:
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
Answer:
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
Answer:
x=−1/3y+3
