0.25r+0.5r

0.75r-0.125=0.5+r

move terms

0.75r-r=0.5+0.125

collect the like terms

-0.25r=0.625

Answer:

r = -2.5

Step-by-step explanation:

0.25r - 0.125 + 0.5r = 0.5 + r

Combine like terms on left side.

0.75r - 0.125 = 0.5 + r

Subtract r from both sides.

-0.25r - 0.125 = 0.5

Add 0.125 to both sides.

-0.25r = 0.625

Divide both sides by -0.25.

r = -2.5
