Someone help me out please

Rufina [12.5K]

Answer:

$\displaystyle x=\frac{5}{4},\;\;1\frac{1}{4}, \;\; or \;\; 1.25$

Step-by-step explanation:

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

Given:

$\displaystyle x+\frac{1}{2} =\frac{7}{4}$

Subtract $\frac{1}{2}$ from both sides of the equation:

$\displaystyle (x+\frac{1}{2})-\frac{1}{2} =(\frac{7}{4})-\frac{1}{2}$

$\displaystyle x=\frac{7}{4}-\frac{1}{2}$

Now, we will create common denominators to simplify.

$\displaystyle x=\frac{7}{4}-\frac{2}{4}$

$\displaystyle x=\frac{5}{4}$
