Question

Solve for x 31=12+1/2x

Answer 1

x = 38

Step-by-step explanation:

First step is to subtract 12 from both sides:

`31=12+(1)/(2)x`
`31-12=12+(1)/(2)x-12`
`31-12=(1)/(2)x`
`19=(1)/(2)x`

Finally, multiplying both sides by 2 gives

`2\cdot19=(1)/(2)x\cdot2`
`38=x`

Hence, the value of x is 38.
