Answer:

(3/8)(10 +x)

Explanation:

The basic idea is that you multiply and divide by 1 in the form of the coefficient of x divided by itself.

`(15)/(4)+(3)/(8)x=(\left((3)/(8)\right))/(\left((3)/(8)\right))\cdot \left((15)/(4)+(3)/(8)x\right)\\\\=\left((3)/(8)\right)\cdot (\left((15)/(4)+(3)/(8)x\right))/(\left((3)/(8)\right))=\left((3)/(8)\right)\cdot \left((15)/(4)\cdot (8)/(3)+x\right)\\\\=\boxed{(3)/(8)(10+x)}`
