x+0.5x+0.2x=51

x + 0.5 x + 0.2 x = 51

x = 30

Solution steps

x + 0.5 x + 0.2 x = 51

Add similar elements:

x + 0.5 x + 0.2 x = 1.7 x

1.7 x = 51

Multiply both sides by

10

17 x = 510

Divide both sides by

17

x = 30

c x - 4 = 7

\frac{3 m - 1}{5} - \frac{m - 4}{3} = 1

5 (2 x - 1) + 7 = 3 (4 x + 1) - 2 x - 1

10 x - 4 = 60 + 2 x

2 - \frac{3 ( x - 5 )}{10} = \frac{x - 3}{5}
