Solve s=1+x/2

$$s = \frac { 1 + x } { 2 }$$

Solve for x

$$x=2s-1$$

Steps for Solving Linear Equation

Divide each term of 1+x by 2 to get \frac{1}{2}+\frac{1}{2}x.

$$s=\frac{1}{2}+\frac{1}{2}x$$

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

$$\frac{1}{2}+\frac{1}{2}x=s$$

Subtract \frac{1}{2} from both sides.

$$\frac{1}{2}x=s-\frac{1}{2}$$

Multiply both sides by 2.

$$\frac{\frac{1}{2}x}{\frac{1}{2}}=\frac{s-\frac{1}{2}}{\frac{1}{2}}$$

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

$$x=\frac{s-\frac{1}{2}}{\frac{1}{2}}$$

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

$$x=2s-1$$

Solve for s

$$s=\frac{x+1}{2}$$

Solution Steps

Divide each term of 1+x by 2 to get \frac{1}{2}+\frac{1}{2}x.

$$s=\frac{1}{2}+\frac{1}{2}x$$
