4/9 (3-x)+x=8

\frac{4}{9} (3 - x) + x = 8

x = 12

Solution steps

\frac{4}{9} (3 - x) + x = 8

Multiply both sides by

9

4 (3 - x) + 9 x = 72

Expand

4 (3 - x) : 12 - 4 x

12 - 4 x + 9 x = 72

Add similar elements:

- 4 x + 9 x = 5 x

12 + 5 x = 72

Move

12

to the right side

5 x = 60

Divide both sides by

5

x = 12

y - 7 (y - 7) = (- 9 y + 12) - 9

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

(- 8 - 3) + 2 x = - 2

\frac{\frac{1}{2} X + \frac{1}{3} X}{2} - \frac{1}{2} = 32

x - 15 = - 6
