2 x - x = x

5 x - 9 = x + 8 + 3

Add the numbers:

8 + 3 = 11

5 x - 9 = x + 11

Move

9

to the right side

5 x = x + 20

Move

x

to the left side

4 x = 20

Divide both sides by

4

x = 5

x, 9 x + 11 y = - 14

y = (- 1)^{2} - 4

2 (x - 5 + 2) = 6

- 6 \frac{1}{4} - 1 \frac{1}{2} x = 2 \frac{1}{2} x + 9 \frac{3}{4}

x, - \frac{1}{3} y + 4 x = 3
