Solve for x: 19.2 x-15=7.5x + 8.4

x = 2

Step-by-step explanation:

1. Combine multiplied terms into a single fraction

19.2 − 15 = 7.5 + 8.4

96/5 − 15 = 7.5x + 8.4

2. Combine multiplied terms into a single fraction again

96/5 − 15 = 7.5x + 8.4

96/5 − 15 = 15x/2 + 8.4

3. Add 15 to both sides of the equation

96/5 − 15 = 15x/2 + 8.4

96/5 − 15 + 15 = 15x/2 + 8.4 + 15

4. Simplify

        96/5 = 15x/2 + 8.4 +1.5

         96/5 = 15x/2 + 23.4

5. Multiply all terms by the same value to eliminate fraction denominators

96/5 = 15x/2 + 23.4

2 x 5 x 96/5 = 2 x 5(15x/2 + 23.4)

7. solution

x=2

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
