Solve 1/2x+4+21=3x

$$\frac { 1 } { 2 } x + 4 + 21 = 3 x$$

Solve for x

$$x=10$$

Steps for Solving Linear Equation

Add 4 and 21 to get 25.

$$\frac{1}{2}x+25=3x$$

Subtract 3x from both sides.

$$\frac{1}{2}x+25-3x=0$$

Combine \frac{1}{2}x and -3x to get -\frac{5}{2}x.

$$-\frac{5}{2}x+25=0$$

Subtract 25 from both sides. Anything subtracted from zero gives its negation.

$$-\frac{5}{2}x=-25$$

Multiply both sides by -\frac{2}{5}, the reciprocal of -\frac{5}{2}.

$$x=-25\left(-\frac{2}{5}\right)$$

Express -25\left(-\frac{2}{5}\right) as a single fraction.

$$x=\frac{-25\left(-2\right)}{5}$$

Multiply -25 and -2 to get 50.

$$x=\frac{50}{5}$$

Divide 50 by 5 to get 10.

$$x=10$$
