x+x/2+2x=84

x + \frac{x}{2} + 2 x = 84

x = 24

Solution steps

x + \frac{x}{2} + 2 x = 84

Add similar elements:

x + 2 x = 3 x

3 x + \frac{x}{2} = 84

Multiply both sides by

2

7 x = 168

Divide both sides by

7

x = 24

4 (x - 5) + 1 + 3 x = - 12

4 x - 3 (x - 5) = 9 (x - 3) + 4 (4 - 2 x)

1 - 2 x + 7 x = 3 (2 x + 1)

\frac{x}{5} + \frac{x}{7} = 1

a x + b = c (x - a)
