Answer:
x = 10
Step-by-step explanation:
[tex]3 - \frac{3}{4}x = \frac{1}{4}x - 7[/tex]
Start by subtracting 3 to both sides
[tex]-\frac{3}{4}x = \frac{1}{4}x-10[/tex]
Subtract 1/4x from both sides ( -3/4 - 1/4 ) = - 1
[tex]-x = -10[/tex]
Divide both sides by a negativ 1 to get rid of the negative
∴ [tex]x = 10[/tex]
