Solve 21+11x=0+13x

$$21 + 11 x = 0 + 13 x$$

Solve for x

$$x = \frac{21}{2} = 10\frac{1}{2} = 10.5$$

Steps for Solving Linear Equation

Anything plus zero gives itself.

$$21+11x=13x$$

Subtract 13x from both sides.

$$21+11x-13x=0$$

Combine 11x and -13x to get -2x.

$$21-2x=0$$

Subtract 21 from both sides. Anything subtracted from zero gives its negation.

$$-2x=-21$$

Divide both sides by -2.

$$x=\frac{-21}{-2}$$

Fraction \frac{-21}{-2} can be simplified to \frac{21}{2} by removing the negative sign from both the numerator and the denominator.

$$x=\frac{21}{2}$$
