Solve b=a/2

$$b = \frac { a } { 2 }$$

Solve for a

$$a=2b$$

Steps for Solving Linear Equation

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

$$\frac{a}{2}=b$$

The equation is in standard form.

$$\frac{1}{2}a=b$$

Multiply both sides by 2.

$$\frac{\frac{1}{2}a}{\frac{1}{2}}=\frac{b}{\frac{1}{2}}$$

Dividing by \frac{1}{2} undoes the multiplication by \frac{1}{2}.

$$a=\frac{b}{\frac{1}{2}}$$

Divide b by \frac{1}{2} by multiplying b by the reciprocal of \frac{1}{2}.

$$a=2b$$

Solve for b

$$b=\frac{a}{2}$$
