Solve for x 1.2x+4.3=2.1-x

$1.2 x + 4.3 = 2.1 - x$

Step 1

Move all terms containing $x$ to the left side of the equation.

Add $x$ to both sides of the equation.

$1.2 x + 4.3 + x = 2.1$

Add $1.2 x$ and $x$ .

$2.2 x + 4.3 = 2.1$

Step 2

Move all terms not containing $x$ to the right side of the equation.

Subtract $4.3$ from both sides of the equation.

$2.2 x = 2.1 - 4.3$

Subtract $4.3$ from $2.1$ .

$2.2 x = - 2.2$

Step 3

Divide each term in $2.2 x = - 2.2$ by $2.2$ and simplify.

Divide each term in $2.2 x = - 2.2$ by $2.2$ .

$\frac{2.2 x}{2.2} = \frac{- 2.2}{2.2}$

Simplify the left side.

Cancel the common factor of $2.2$ .

Cancel the common factor.

$\frac{2.2 x}{2.2} = \frac{- 2.2}{2.2}$

Divide $x$ by $1$ .

$x = \frac{- 2.2}{2.2}$

Simplify the right side.

Divide $- 2.2$ by $2.2$ .

$x = - 1$
