2x + 4(x - 1) = 2 +4x

Answer:
x = 3
Step-by-step explanation:
First distribute
2x + 4x - 4 = 2 + 4x
combine like terms
6x - 4 = 2 + 4x
continue
2x - 4 = 2
add 4 to both sides
2x = 6
divide both sides by 2
x = 3
2x+4(x-1)=2+4x.
Distribute the 4 into (x-1).
2x+4x-4=2+4x
Now add x’s
6x-4=2+4x
Solve for x.
(Move x to same side)
6x-4x-4=2+4x-4x.
Then do the same with -4.
2x-4+4=2+4.
2x=6
Divide 2 by both sides: 6/2
Your answer will be once divided : 3

We know this because the proportion can be used to find another answer.
Example:
How many feet did the elevator ascend in 0.25 minutes?
750 x
---------- = ----------
1 0.25
750(0.25) = 1x
