4.5 x - 5.2 = 4

$4.5 x - 5.2 = 4$

Step 1

Move all terms not containing

x

$x$ to the right side of the equation.

Step 1.1

Add

5.2

$5.2$ to both sides of the equation.

4.5 x = 4 + 5.2

$4.5 x = 4 + 5.2$

Step 1.2

Add

4

$4$ and

5.2

$5.2$ .

4.5 x = 9.2

$4.5 x = 9.2$

4.5 x = 9.2

$4.5 x = 9.2$

Step 2

Divide each term in

4.5 x = 9.2

$4.5 x = 9.2$ by

4.5

$4.5$ and simplify.

Step 2.1

Divide each term in

4.5 x = 9.2

$4.5 x = 9.2$ by

4.5

$4.5$ .

\frac{4.5 x}{4.5} = \frac{9.2}{4.5}

$\frac{4.5 x}{4.5} = \frac{9.2}{4.5}$

Step 2.2

Simplify the left side.

Step 2.2.1

Cancel the common factor of

4.5

$4.5$ .

Step 2.2.1.1

Cancel the common factor.

\frac{4.5 x}{4.5} = \frac{9.2}{4.5}

$\frac{4.5 x}{4.5} = \frac{9.2}{4.5}$

Step 2.2.1.2

Divide

x

$x$ by

1

$1$ .

x = \frac{9.2}{4.5}

$x = \frac{9.2}{4.5}$

x = \frac{9.2}{4.5}

$x = \frac{9.2}{4.5}$

x = \frac{9.2}{4.5}

$x = \frac{9.2}{4.5}$

Step 2.3

Simplify the right side.

Step 2.3.1

Divide

9.2

$9.2$ by

4.5

$4.5$ .

x = 2.0\overline{4}

$x = 2.0\overline{4}$

x = 2.0\overline{4}

$x = 2.0\overline{4}$

x = 2.0\overline{4}

$x = 2.0\overline{4}$
