Solve for m. 7/10=r - (-8/5)

-9/10 = r

Step-by-step explanation:

7/10=r - (-8/5)

Subtracting a negative is like adding

7/10=r + (8/5)

Subtract 8/5 from each side

7/10 - 8/5=r + (8/5) - 8/5

7/10 - 8/5 = r

Get a common denominator

7/10 - 16/10 = r

-9/10 = r

Step-by-step explanation:

7/10=r - (-8/5)

7/10=r+8/5

7/10 - 8/5 = r + 8/5 - 8/5

7/10 - 8/5 = r

7/10 - 16/10 = r

-9/10 = r

r = - 0.9
