r-3/4=2r-এর সমাধান করুন

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

Solve for r

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

Steps for Solving Linear Equation

Multiply both sides of the equation by 4.

$$r-3=8r$$

Subtract 8r from both sides.

$$r-3-8r=0$$

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

$$-7r-3=0$$

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

$$-7r=3$$

Divide both sides by -7.

$$r=\frac{3}{-7}$$

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

$$r=-\frac{3}{7}$$
