3*(13-3y)/2+y=9

3 \cdot \frac{13 - 3 y}{2} + y = 9

y = 3

Solution steps

3 \cdot \frac{13 - 3 y}{2} + y = 9

Expand

3 \cdot \frac{13 - 3 y}{2} + y : \frac{39}{2} - \frac{7 y}{2}

\frac{39}{2} - \frac{7 y}{2} = 9

Multiply both sides by

2

39 - 7 y = 18

Move

39

to the right side

- 7 y = - 21

Divide both sides by

- 7

y = 3

2 x - 6 = 5 (x - 6)

x + 2 = \frac{7}{8} x - 15

- 5 (m - 4) = 13 - 6 m

2 (x - p) = p^{2} (1 - x)

(3 a^{2} + 9) 2 = 9 a^{4} + y + 81
