Solve l+2/9=1/9+7/9

$$l + \frac { 2 } { 9 } = \frac { 1 } { 9 } + \frac { 7 } { 9 }$$

Solve for l

$$l=\frac{2}{3}\approx 0.666666667$$

Steps for Solving Linear Equation

Since \frac{1}{9} and \frac{7}{9} have the same denominator, add them by adding their numerators.

$$l+\frac{2}{9}=\frac{1+7}{9}$$

Add 1 and 7 to get 8.

$$l+\frac{2}{9}=\frac{8}{9}$$

Subtract \frac{2}{9} from both sides.

$$l=\frac{8}{9}-\frac{2}{9}$$

Since \frac{8}{9} and \frac{2}{9} have the same denominator, subtract them by subtracting their numerators.

$$l=\frac{8-2}{9}$$

Subtract 2 from 8 to get 6.

$$l=\frac{6}{9}$$

Reduce the fraction \frac{6}{9} to lowest terms by extracting and canceling out 3.

$$l=\frac{2}{3}$$
