Solve 2(10-x)=15

$$2 ( 10 - x ) = 15$$

Solve for x

$$x = \frac{5}{2} = 2\frac{1}{2} = 2.5$$

Steps for Solving Linear Equation

Divide both sides by 2.

$$10-x=\frac{15}{2}$$

Subtract 10 from both sides.

$$-x=\frac{15}{2}-10$$

Convert 10 to fraction \frac{20}{2}.

$$-x=\frac{15}{2}-\frac{20}{2}$$

Since \frac{15}{2} and \frac{20}{2} have the same denominator, subtract them by subtracting their numerators.

$$-x=\frac{15-20}{2}$$

Subtract 20 from 15 to get -5.

$$-x=-\frac{5}{2}$$

Multiply both sides by -1.

$$x=\frac{5}{2}$$
