Question

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

Answer 1

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
