0.25r-0.125+0.5r=0.5+r

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

r=-2.5

Step-by-step explanation:

collect like terms

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

divide both sides by - 0.25 to get your answer.
