-r+3-1/9 r=2r+1-8/9 r

- r + 3 - \frac{1}{9} r = 2 r + 1 - \frac{8}{9} r

r = \frac{9}{10}

Decimal Notation

r = 0.9

Solution steps

- r + 3 - \frac{1}{9} r = 2 r + 1 - \frac{8}{9} r

Move

3

to the right side

- r - \frac{1}{9} r = \frac{10}{9} r - 2

Move

\frac{10}{9} r

to the left side

- \frac{20}{9} r = - 2

Multiply both sides by

9

- 20 r = - 18

Divide both sides by

- 20

r = \frac{9}{10}

- 0.1 + 0.9 a = 2.15

4 x + 3 [x - 2 (2 x - 1)] = 4 - 3 x

\frac{8}{9} (\frac{1}{2} v - 18) + 2 v = \frac{2}{3} v

x, 2 x - 9 y = 18

7 - x = 3
