x+2x+x/2+15=99

x + 2 x + \frac{x}{2} + 15 = 99

x = 24

Solution steps

x + 2 x + \frac{x}{2} + 15 = 99

Add similar elements:

x + 2 x = 3 x

3 x + \frac{x}{2} + 15 = 99

Move

15

to the right side

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

Multiply both sides by

2

7 x = 168

Divide both sides by

7

x = 24

10 x + 8 + 7 x + 2 = 180

48 - 2 x = 54 - 8 x

y, y - 2 x = 5

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

y - 2 y = 7
