Given equation is , [tex]\frac{1}{4}x + 5 = 7[/tex]
To find x, first add - 5 on both sides
[tex]\frac{1}{4}x + 5 - 5 = 7 - 5[/tex]
[tex]\frac{1}{4}x = 2[/tex]
Multiply both side by 4 to isolate x
[tex]4\times \frac{1}{4} x + 5 = 2 \times 4[/tex]
[tex]1\times x = 2\times 4[/tex]
Now to find x, divide both side by 1
[tex]\frac{1x}{1}= \frac{8}{1}[/tex]
x = 8
So option 3 is the answer
