Solve D(2)-2+T=22

$$D ( 2 ) - 2 + T = 22$$

Solve for D

$$D=-\frac{T}{2}+12$$

Steps for Solving Linear Equation

Add 2 to both sides.

$$D\times 2+T=22+2$$

Add 22 and 2 to get 24.

$$D\times 2+T=24$$

Subtract T from both sides.

$$D\times 2=24-T$$

The equation is in standard form.

$$2D=24-T$$

Divide both sides by 2.

$$\frac{2D}{2}=\frac{24-T}{2}$$

Dividing by 2 undoes the multiplication by 2.

$$D=\frac{24-T}{2}$$

Divide 24-T by 2.

$$D=-\frac{T}{2}+12$$

Solve for T

$$T=24-2D$$

Solution Steps

Subtract D\times 2 from both sides.

$$-2+T=22-D\times 2$$

Add 2 to both sides.

$$T=22-D\times 2+2$$

Multiply -1 and 2 to get -2.

$$T=22-2D+2$$

Add 22 and 2 to get 24.

$$T=24-2D$$
