Question

15x + 20= 2.5x + 5.00

Answer 1

x=-1.2

Explanation:

Question: 15x+20=2.5x+5

1) Subtract 2.5x from both sides:

12.5x+20=5

2) Subtract 20 from both sides:

12.5x=-15

3) Divide both sides by 12.5:

x=-15/12.5

4) Write the fraction as a decimal:

x=-1.2

Answer 2

-1.2

Explanation:

15x+20−2.5x=2.5x+5−2.5x

12.5x+20=5

12.5x+20−20=5−20

12.5x=−15

12.5x /12.5 =

−15 /12.5

x=−1.2
