Solve Delta-D=19-22

$$\Delta - D = 19 - 22$$

Solve for D

$$D=\Delta +3$$

Steps for Solving Linear Equation

Subtract 22 from 19 to get -3.

$$\Delta -D=-3$$

Subtract \Delta from both sides.

$$-D=-3-\Delta$$

The equation is in standard form.

$$-D=-\Delta -3$$

Divide both sides by -1.

$$\frac{-D}{-1}=\frac{-\Delta -3}{-1}$$

Dividing by -1 undoes the multiplication by -1.

$$D=\frac{-\Delta -3}{-1}$$

Divide -3-\Delta by -1.

$$D=\Delta +3$$

Solve for Δ

$$\Delta =D-3$$

Solution Steps

Subtract 22 from 19 to get -3.

$$\Delta -D=-3$$

Add D to both sides.

$$\Delta =-3+D$$
