Combining like terms 2 + 3x - X=4x

Mathematics

Answer:

Hi there!

Your answer is:

x= 1

Step-by-step explanation:

Goal- get all X's on one side, and all whole numbers on the other

2+3x -x = 4x

First, combine like terms on each side of the equal sign

2+ 2x = 4x

Next, think about the additive inverse property. What, added to 2x, equals 0? 2x + (-2x) =0! So, we <u>subtract</u> 2x from both sides!

2= 4x-2x

Simplify

2= 2x

Divide both sides by the coefficient of x (in this case, 2)

2/2 = x

2/2 is equal to 1

1= x

Hope this helps!

Answer:

x = 1

Step-by-step explanation:

Combining the x terms, we get  

2 + 2x = 4x, or 2 = 2x.

Then, after we divide both sides by 2 to isolate x, we get x = 1

spin [16.1K]

9514 1404 393

Answer:

  7x^3 +11x^2 -5x -8

Step-by-step explanation:

Combine like terms.

  (4x^3+6x^2+2x^2-3) + (3x^3+3x^2-5x-5)

  = (4 +3)x^3 +(6 +2 +3)x^2 +(-5)x + (-3 -5)

  = 7x^3 +11x^2 -5x -8

_____

Noting that the first expression contains two x^2 terms, we wonder if you actually want the sum ...

  (4x^3+6x^2+2x-3) + (3x^3+3x^2-5x-5)

  = (4 +3)x^3 +(6 +3)x^2 +(2 -5)x +(-3 -5)

  = 7x^3 +9x^2 -3x -8
