Step 1.1

Add $7.3$ and $1.3$ .

$- 0.2 x + 8.6 - 0.6 x = 12 - 0.8 x - 3.6$

Step 1.2

Subtract $0.6 x$ from $- 0.2 x$ .

$- 0.8 x + 8.6 = 12 - 0.8 x - 3.6$

Step 2

Subtract $3.6$ from $12$ .

$- 0.8 x + 8.6 = - 0.8 x + 8.4$

Step 3

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

Step 3.1

Add $0.8 x$ to both sides of the equation.

$- 0.8 x + 8.6 + 0.8 x = 8.4$

Step 3.2

Add $- 0.8 x$ and $0.8 x$ .

$0 x + 8.6 = 8.4$

Step 3.3

Multiply $0$ by $x$ .

$0 + 8.6 = 8.4$

Step 3.4

Add $0$ and $8.6$ .

$8.6 = 8.4$

Step 4

Since $8.6 \neq 8.4$ , there are no solutions.
