Jan 31, 2016

See solution below

Explanation:

$\frac{9}{2} x$ + 7 = 25

$\frac{9}{2} x$ = 18

9x = 18(2)

9x = 36

x = 4

Your solution is x = 4

Practice exercises:

1. Solve each equation.

a) $\frac{2}{3} x$ - 5 = 22

b) 2x + 3 = 4 - 5x

c) $\frac{3 x + 4}{2}$= $\frac{8 x + 4}{4}$

d) $\frac{x}{3}$ + $\frac{2 x + 1}{4}$ = $\frac{3 x - 2}{6}$

Good luck!
