Solve for r

r=-\frac{3}{7}\approx -0.428571429

$r=−73 ≈−0.428571429$

Steps for Solving Linear Equation

\frac{r-3}{4}=2r

$4r−3 =2r$

Multiply both sides of the equation by 4.

Multiply both sides of the equation by $4$.

r-3=8r

$r−3=8r$

Subtract 8r from both sides.

Subtract $8r$ from both sides.

r-3-8r=0

$r−3−8r=0$

Combine r and -8r to get -7r.

Combine $r$ and $−8r$ to get $−7r$.

-7r-3=0

$−7r−3=0$

Add 3 to both sides. Anything plus zero gives itself.

Add $3$ to both sides. Anything plus zero gives itself.

-7r=3

$−7r=3$

Divide both sides by -7.

Divide both sides by $−7$.

r=\frac{3}{-7}

$r=−73 $

Fraction \frac{3}{-7}\approx -0.428571429 can be rewritten as -\frac{3}{7}\approx -0.428571429 by extracting the negative sign.

Fraction $−73 ≈−0.428571429$ can be rewritten as $−73 ≈−0.428571429$ by extracting the negative sign.

r=-\frac{3}{7}

$r=−73 $
