Solve 300+a/39=300/18

$$\frac { 300 + a } { 39 } = \frac { 300 } { 18 }$$

Solve for a

$$a=350$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 234, the least common multiple of 39,18.

$$6\left(300+a\right)=13\times 300$$

Use the distributive property to multiply 6 by 300+a.

$$1800+6a=13\times 300$$

Multiply 13 and 300 to get 3900.

$$1800+6a=3900$$

Subtract 1800 from both sides.

$$6a=3900-1800$$

Subtract 1800 from 3900 to get 2100.

$$6a=2100$$

Divide both sides by 6.

$$a=\frac{2100}{6}$$

Divide 2100 by 6 to get 350.

$$a=350$$
