3x-0.4 (5-2x) = 5.6 how do i figure this out

First, you need to distribute in the parentheses.

-0.4 (5 - 2x) = - 2 + 0.8x

Next, you simplify.

3x - 2 + 0.8x = 5.6

3.8x - 2 = 5.6

Then you try to isolate x (by adding 2 to both sides of the equation in this place, then dividing by 3.8).

3.8x - 2 = 5.6

+2 + 2

3.8x = 7.6

/3.8 / 3.8

x = 2

You’re final answer is x=2

3x - 0.4 (5-2x) = 5.6

First multiply - 0.4 (5 - 2x) which is - 2 + 0.8x

Now we have 3x - 2 + 0.8x = 5.6

Then add 3x + 0.8x which is 3.8x and plug it back in which is

3.8x - 2 = 5.6

-2 - 2

3.8x = 3.6 and divide both sided by 3.8

and the answer is x = 0.94736842105
