90(x+1/2)-100x=15

90 (x + \frac{1}{2}) - 100 x = 15

x = 3

Solution steps

90 (x + \frac{1}{2}) - 100 x = 15

Expand

90 (x + \frac{1}{2}) - 100 x : - 10 x + 45

- 10 x + 45 = 15

Move

45

to the right side

- 10 x = - 30

Divide both sides by

- 10

x = 3

\frac{x}{7} = 12

2 x + 3 + 3 (x - 1) = 2 (x + 2)

x^{2} + 1 = (x + 1) (x + 1)

\frac{1}{2} x = - 4

- 6 x - 4 = - 10 x - 16 - 10 x - 16
