Answer: [ 4x + 2x + 6 ] is not an equation.
It makes no statement, and asks no question, so nothing there needs to be solved.
The terms could be combined for a neater appearance:
4x + 2x + 6 = 6x + 6 = 6 (x + 1)
but that doesn't change anything, and it's not a solution or an answer to anything.
It's just a different way of writing the same thing.
Answer: It is not an equation, since it has no equal sign.

y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)
2x+4-x = 4x-5 2x-x-4x = -5-4 -3x = -9 x = 3
4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3
To solve for x, set up the equation: 2x +2x = 40 (then simplify) 4x = 40 (then divide both sides of the equation by 4) x = 10 (this is the answer)
2x + 2x + 146 + 26 = 172 4x + 172 = 172 4x = 0 x = 0
