Solve 12=R*125/R+1

$$12 = \frac { R \times 125 } { R + 1 }$$

Solve for R

$$R=\frac{12}{113}\approx 0.10619469$$

Steps for Solving Linear Equation

Variable R cannot be equal to -1 since division by zero is not defined. Multiply both sides of the equation by R+1.

$$12\left(R+1\right)=R\times 125$$

Use the distributive property to multiply 12 by R+1.

$$12R+12=R\times 125$$

Subtract R\times 125 from both sides.

$$12R+12-R\times 125=0$$

Combine 12R and -R\times 125 to get -113R.

$$-113R+12=0$$

Subtract 12 from both sides. Anything subtracted from zero gives its negation.

$$-113R=-12$$

Divide both sides by -113.

$$R=\frac{-12}{-113}$$

Fraction \frac{-12}{-113} can be simplified to \frac{12}{113} by removing the negative sign from both the numerator and the denominator.

$$R=\frac{12}{113}$$
