15=4.15+.85x
We want find out what the weight can be for his budget.
15=4.15+0.85x
Step 1: Simplify both sides of the equation.
15=0.85x+4.15
Step 2: Flip the equation.
0.85x+4.15=15
Step 3: Subtract 4.15 from both sides.
0.85x+4.15−4.15=15−4.15
0.85x=10.85
Step 4: Divide both sides by 0.85.
10.85/0.85=.85x/.85
