Solve 71/4-21/3=7

$$7 \frac { 1 } { 4 } - 2 \frac { 1 } { 3 } = 7$$

Verify

Solution Steps

Multiply both sides of the equation by 12, the least common multiple of 4,3.

$$3\left(7\times 4+1\right)-4\left(2\times 3+1\right)=84$$

Multiply 7 and 4 to get 28.

$$3\left(28+1\right)-4\left(2\times 3+1\right)=84$$

Add 28 and 1 to get 29.

$$3\times 29-4\left(2\times 3+1\right)=84$$

Multiply 3 and 29 to get 87.

$$87-4\left(2\times 3+1\right)=84$$

Multiply 2 and 3 to get 6.

$$87-4\left(6+1\right)=84$$

Add 6 and 1 to get 7.

$$87-4\times 7=84$$

Multiply -4 and 7 to get -28.

$$87-28=84$$

Subtract 28 from 87 to get 59.

$$59=84$$

Compare 59 and 84.

$$\text{false}$$
