Solve -5-21/2=quad71/2-15/2

$$- 5 - 2 \frac { 1 } { 2 } = \quad 7 \frac { 1 } { 2 } - \frac { 15 } { 2 }$$

Verify

Solution Steps

Multiply both sides of the equation by 2.

$$-10-\left(2\times 2+1\right)=7\times 2+1-15$$

Multiply 2 and 2 to get 4.

$$-10-\left(4+1\right)=7\times 2+1-15$$

Add 4 and 1 to get 5.

$$-10-5=7\times 2+1-15$$

Subtract 5 from -10 to get -15.

$$-15=7\times 2+1-15$$

Multiply 7 and 2 to get 14.

$$-15=14+1-15$$

Add 14 and 1 to get 15.

$$-15=15-15$$

Subtract 15 from 15 to get 0.

$$-15=0$$

Compare -15 and 0.

$$\text{false}$$
