Solve A=2b-c^22

$$A = 2 b - c ^ { 2 } 2$$

Solve for b

$$b=c^{2}+\frac{A}{2}$$

Steps for Solving Linear Equation

Swap sides so that all variable terms are on the left hand side.

$$2b-c^{2}\times 2=A$$

Add c^{2}\times 2 to both sides.

$$2b=A+c^{2}\times 2$$

The equation is in standard form.

$$2b=A+2c^{2}$$

Divide both sides by 2.

$$\frac{2b}{2}=\frac{A+2c^{2}}{2}$$

Dividing by 2 undoes the multiplication by 2.

$$b=\frac{A+2c^{2}}{2}$$

Divide 2c^{2}+A by 2.

$$b=c^{2}+\frac{A}{2}$$

Solve for A

$$A=2\left(b-c^{2}\right)$$

Solution Steps

Multiply -1 and 2 to get -2.

$$A=2b-2c^{2}$$
