r/3 =(r-10)/9

\frac{r}{3} = \frac{r - 10}{9}

r = - 5

Solution steps

\frac{r}{3} = \frac{r - 10}{9}

Apply fraction cross multiply: if

\frac{a}{b} = \frac{c}{d}

then

a \cdot d = b \cdot c

r \cdot 9 = 3 (r - 10)

Expand

3 (r - 10) : 3 r - 30

r \cdot 9 = 3 r - 30

Move

3 r

to the left side

6 r = - 30

Divide both sides by

6

r = - 5

\frac{b - 3}{4} = 6

- (x - 2 (3 - x) - 2) = 2

- 4 x + 2 = - 34

4 (- x + 4) = - 8

3 = 0.098 d + 1
