Pllllllsssssss help quick and accurately

Answer:
r = [tex]\frac{-9}{10}[/tex]
Step-by-step 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!
Answer:
[tex]r=\frac{-9}{10}[/tex]
Step-by-step explanation:
[tex]\frac{7}{8}=r-(\frac{-8}{5})[/tex]
opening bracket will change the sign
[tex]\frac{7}{10}=r+\frac{8}{5}[/tex]
in oreder to find the value of subtract [tex]\frac{8}{5}[/tex] on both sides
[tex]\frac{7}{10} - \frac{8}{5}[/tex]=r
taking LCM
[tex]\frac{7}{10}-\frac{8*2}{5*2}[/tex]=r
[tex]\frac{7}{10}-\frac{16}{10}=r[/tex]
[tex]\frac{-9}{10}=r[/tex]
i hope it will help you :)
