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

Solve the following equations: <br> 5x-(x+2)^2=x^2-8+x
Blababa [14]

Answer:

x = √2 = 1.414

Step-by-step explanation:

5x-(x+2)^2=x^2-8+x

since (x+2)^2 = x^2 + 2(x)(2) + 2^2 = x^2 + 4x + 4

so

5x - (x^2 + 4x + 4) = x^2 + x - 8

-x^2 + x - 4 = x^2 + x - 8

x^2 + x^2 + x - x = -4 + 8

2x^2 = 4

x^2 = 2

x = √2 = 1.414
