Step-by-step explanation:

Hey there!

Given;

[tex] \frac{5}{2} x - 7 = \frac{3}{4} x + 14[/tex]

Bring "3/4x" on left side and "-7" in right side.

[tex] \frac{5}{2} x - \frac{3}{4} x = 14 + 7[/tex]

Simplify it.

[tex] \frac{5 \times 2x - 3x}{4} = 21[/tex]

[tex] \frac{10x - 3x}{4} = 21[/tex]

[tex]7x = 21 \times 4[/tex]

7x = 84

X = 84/7

Therefore, X= 12.

check:

5/2*12-7=3/4*12+14

23=23 {true}

Hope it helps....
