Solve x=(1)(s)+(1)(4)/2

$$x = \frac { ( 1 ) ( s ) + ( 1 ) ( 4 ) } { 2 }$$

Solve for s

$$s=2\left(x-2\right)$$

Steps for Solving Linear Equation

Multiply 1 and 4 to get 4.

$$x=\frac{1s+4}{2}$$

Divide each term of 1s+4 by 2 to get \frac{1}{2}s+2.

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

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

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

Subtract 2 from both sides.

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

Multiply both sides by 2.

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

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

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

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

$$s=2x-4$$

Solve for x

$$x=\frac{s+4}{2}$$

Solution Steps

Multiply 1 and 4 to get 4.

$$x=\frac{1s+4}{2}$$

Divide each term of 1s+4 by 2 to get \frac{1}{2}s+2.

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