Answer 1

`5(7)/(8) c +7`

Explanation:

The like terms are the ones containing the variable 'c'. They are combined by adding their coefficients.

Working just with the coefficients of c, we have ...

`2(3)/(4) +3(1)/(8)=(2+3)+\left((6)/(8)+(1)/(8)\right)=5(7)/(8)`

Then the simplified expression is ...

(2 3/4)c +(3 1/8)c +7

= (5 7/8)c +7
