Question

Someone help me out please

Answer 1

`\displaystyle x=(5)/(4),\;\;1(1)/(4), \;\; or \;\; 1.25`

Explanation:

To solve for x, we need to isolate the x variable.

Given:

`\displaystyle x+(1)/(2) =(7)/(4)`

Subtract
`(1)/(2)` from both sides of the equation:

`\displaystyle (x+(1)/(2))-(1)/(2) =((7)/(4))-(1)/(2)`

`\displaystyle x=(7)/(4)-(1)/(2)`

Now, we will create common denominators to simplify.

`\displaystyle x=(7)/(4)-(2)/(4)`

`\displaystyle x=(5)/(4)`
