(a) 2x + 4 (x - 1) = 2 + 4x
(b) 25 - x = 15 - (3x + 10)
(c) 4x = 2x + 2x + 5 (x - x)

I'd.k the last one

Step-by-step explanation:

I'm just using characters bc it says I need at least 20

Answer:

a) x = 3

b) 4x

c ) 9x - x

Step-by-step explanation:

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

2x + 4x - 4 = 2 + 4x

2x[ + 4x [- 4 = 2 [+ 4x

2x + 4x - 4x = 2+4

2x = 6

(Simply both sides by 2)

X = 3

b)25 - x = 15 - (3x + 10)

25 - x = 15 - 3x + 10

25[ - x = [15[ - 3x [+ 10

25 - 15 - 10 = 3x + x

0 = 4x

4x

c)4x = 2x + 2x + 5 (x - x)

4x = 2x + 2x + 5x - 5x

[+4x =[ 2x[ + 2x[ + 5x[ - 5x

2x+ 2x + 5x -5x - 4x

(2x+ 2x + 5x) (-5x - 4x)

9x - x
