Question

1,2x-1,8+x=3,6+1,8=?

Answer 1

$1.2x - 1.8 + x = 3.6 + 1.8 \\ 2.2x - 1.8 = 5.4 \\ 2.2x = 5.4 + 1.8 \\ 2.2x = 7.2 \\ x = \frac{36}{11}$

Answer 2

To solve the equation:

1. First, combine like terms on both sides of the equation.

1.2x - 1.8 + x = 3.6 + 1.8

Combine the x terms on the left side:

(1.2x + x) - 1.8 = 3.6 + 1.8

Now, simplify:

2.2x - 1.8 = 5.4

2. Add 1.8 to both sides of the equation to isolate the term with x:

2.2x - 1.8 + 1.8 = 5.4 + 1.8

This simplifies to:

2.2x = 7.2

3. Finally, divide both sides by 2.2 to solve for x:

(2.2x)/2.2 = 7.2/2.2

x = 7.2/2.2

x ≈ 3.273

So, the solution to the equation is approximately x ≈ 3.273.
