Solve 2x-3(-21/2)=9

$$2x-3(-2 \frac{ 1 }{ 2 } ) = 9$$

Solve for x

$$x=\frac{3}{4}=0.75$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 2.

$$4x-6\left(-\frac{2\times 2+1}{2}\right)=18$$

Multiply 2 and 2 to get 4.

$$4x-6\left(-\frac{4+1}{2}\right)=18$$

Add 4 and 1 to get 5.

$$4x-6\left(-\frac{5}{2}\right)=18$$

Express 6\left(-\frac{5}{2}\right) as a single fraction.

$$4x-\frac{6\left(-5\right)}{2}=18$$

Multiply 6 and -5 to get -30.

$$4x-\frac{-30}{2}=18$$

Divide -30 by 2 to get -15.

$$4x-\left(-15\right)=18$$

The opposite of -15 is 15.

$$4x+15=18$$

Subtract 15 from both sides.

$$4x=18-15$$

Subtract 15 from 18 to get 3.

$$4x=3$$

Divide both sides by 4.

$$x=\frac{3}{4}$$
