4=(2(u-9))/3

4 = \frac{2 ( u - 9 )}{3}

u = 15

Solution steps

4 = \frac{2 ( u - 9 )}{3}

Switch sides

\frac{2 ( u - 9 )}{3} = 4

Multiply both sides by

3

2 (u - 9) = 12

Divide both sides by

2

u - 9 = 6

Move

9

to the right side

u = 15

19 = 11 u

12 x + 4 = x + (12 mod 13)

4 (2 x - 3) = - 5 (3 - x)

14 - (c + 6) = - 9

f = 8 (- 4) - 6
