Solve 7c-2D-4y=3

$$7 c - 2 D - 4 y = 3$$

Solve for D

$$D=\frac{7c}{2}-2y-\frac{3}{2}$$

Steps for Solving Linear Equation

Subtract 7c from both sides.

$$-2D-4y=3-7c$$

Add 4y to both sides.

$$-2D=3-7c+4y$$

The equation is in standard form.

$$-2D=4y-7c+3$$

Divide both sides by -2.

$$\frac{-2D}{-2}=\frac{4y-7c+3}{-2}$$

Dividing by -2 undoes the multiplication by -2.

$$D=\frac{4y-7c+3}{-2}$$

Divide 3-7c+4y by -2.

$$D=\frac{7c}{2}-2y-\frac{3}{2}$$

Solve for c

$$c=\frac{4y+2D+3}{7}$$

Steps for Solving Linear Equation

Add 2D to both sides.

$$7c-4y=3+2D$$

Add 4y to both sides.

$$7c=3+2D+4y$$

The equation is in standard form.

$$7c=4y+2D+3$$

Divide both sides by 7.

$$\frac{7c}{7}=\frac{4y+2D+3}{7}$$

Dividing by 7 undoes the multiplication by 7.

$$c=\frac{4y+2D+3}{7}$$
