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

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

x = - \frac{23}{2}

Decimal Notation

x = - 11.5

Solution steps

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

Subtract

x

from both sides

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

Simplify

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

Expand

- (2 - x) : - 2 + x

Expand

3 (x + 7) : 3 x + 21

- 2 + x = 3 x + 21

Move

2

to the right side

x = 3 x + 23

Move

3 x

to the left side

- 2 x = 23

Divide both sides by

- 2

x = - \frac{23}{2}

3.6 = 1.5 - 0.7 z

\frac{x - 109600}{10000} = - 1.28

- 2 x = 9 - x

x, 5 x + 3 y = 20

a, ab + c = 5
