Question

Pllllllsssssss help quick and accurately

Answer 1

`r=(-9)/(10)`

Explanation:

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

opening bracket will change the sign

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

in oreder to find the value of subtract
`(8)/(5)` on both sides

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

taking LCM

`(7)/(10)-(8*2)/(5*2)`=r

`(7)/(10)-(16)/(10)=r`

`(-9)/(10)=r`

i hope it will help you :)

Answer 2

r =
`(-9)/(10)`

Explanation:

Step 1: Convert symbols

7/10 = r + 8/5

Step 2: Subtract 8/5 on both sides

r = 7/10 - 8/5

Step 3: Combine like terms

r = -9/10

And we have our final answer!
