Solving Equations

The objective (goal) when solving an equation is to...

What is the inverse operation of division?

What would be the first step to solving the following equation:

$$44\ =\ 11\ -\ 3x$$

Solve for x :

$$14x\ -\ 10\ =\ 4$$

Type in your answer.

IMPORTANT: First type the small letter x, then an equal sign, then the number. NO SPACES.

(a)  

Solve for x :

$$-16\ =\ -5x\ -\ 1$$

Type in your answer.

IMPORTANT: First type the small letter x, then an equal sign, then the number. NO SPACES.

Solve for x :

$$\frac{x}{0.8}\ -\ 1.4\ =\ 0.6$$

Type in your answer.

IMPORTANT: First type the small letter x, then an equal sign, then the number. NO SPACES.

Solve for x :

$$-9\ =\ \frac{x}{5}+7$$

Type in your answer.

IMPORTANT: First type the small letter x, then an equal sign, then the number. NO SPACES.

(a)  

Solve for x :

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

Given the equation:

$$10\ =\ \frac{x}{4}+8$$

Does x=8?

Verify by replacing the x in the equation with 8.

Given the equation:

$$-19\ =\ -4x\ -\ 7$$

Does x=7?

Verify by replacing the x in the equation with 7.
