x/3 =3(x-3)-7

\frac{x}{3} = 3 (x - 3) - 7

x = 6

Solution steps

\frac{x}{3} = 3 (x - 3) - 7

Multiply both sides by

3

x = 9 (x - 3) - 21

Expand

9 (x - 3) - 21 : 9 x - 48

x = 9 x - 48

Move

9 x

to the left side

- 8 x = - 48

Divide both sides by

- 8

x = 6

x, 4 x + 3 y = 3

x + 4 = 3 (x + 12)

y = 2 (1) - 1

q, - 7 q + 12 r = 3 q - 4 r

3 x (3 - 2 + 7) = - x + 2 x - 23
