Answer:
1: Y=0.8x+72 = x=1.25y−90
2: 20x+32y=43 = x= -8/5y + 43/20
First question steps:
Solved for x
Step 1: Flip the equation.
Step 2: Add -72 to both sides.
Step 3: Divide both sides by 0.8.
Second question steps:
Step 1: Add -32y to both sides.
Step 2: Divide both sides by 20.
Answer:
1: Y=0.8x+72 = x=1.25y−90
2: 20x+32y=43 = x= -8/5y + 43/20
