-3/10 x+1=10

- \frac{3}{10} x + 1 = 10

x = - 30

Solution steps

- \frac{3}{10} x + 1 = 10

Move

1

to the right side

- \frac{3}{10} x = 9

Multiply both sides by

10

- 3 x = 90

Divide both sides by

- 3

x = - 30

13 x + 1 = 2 x + 12

x, 2 y - x = 8

- 5 x - (- 7 - 4 x) = - 2 (3 x - 4)

4 (x - 2.5) = 7 (12.2 - 0.5 x)

(3 x + 5) \cdot (2 x + 4) = 6 x^{2} - 2
