75+2x+5x=3(120-x)

75 + 2 x + 5 x = 3 (120 - x)

x = \frac{57}{2}

Decimal Notation

x = 28.5

Solution steps

75 + 2 x + 5 x = 3 (120 - x)

Add similar elements:

2 x + 5 x = 7 x

75 + 7 x = 3 (120 - x)

Expand

3 (120 - x) : 360 - 3 x

75 + 7 x = 360 - 3 x

Move

75

to the right side

7 x = - 3 x + 285

Move

3 x

to the left side

10 x = 285

Divide both sides by

10

x = \frac{57}{2}

3 (a - 2) - (a + 6) = 4 (a - 1)

- 91 = 10 p + 9

x + (x - 6) = 90

4 (x + 7) = 2 (x + 12) + 2 (x + 1)

x, 3 x = 2 y - 4
