-13=5(1+4x)-2x

- 13 = 5 (1 + 4 x) - 2 x

x = - 1

Solution steps

- 13 = 5 (1 + 4 x) - 2 x

Switch sides

5 (1 + 4 x) - 2 x = - 13

Expand

5 (1 + 4 x) : 5 + 20 x

5 + 20 x - 2 x = - 13

Add similar elements:

20 x - 2 x = 18 x

5 + 18 x = - 13

Move

5

to the right side

18 x = - 18

Divide both sides by

18

x = - 1

5 (- x + 1) = - 3 (5 x - 6)

b = 3 \frac{v}{h}

a, 2 a + b = 3 b

\frac{x}{7} - 1 = \frac{x}{9} + 1

a x + 2 (4 - 3 x) = 10
