Question

a) x/2 + 2/3 = 2x/3 - 2(x+2)

b) 2x + 5x + 3 - 4X = 4(2x - 8)

Answer 1

a) x + 2 = 2x - 2.(x+2)

2 3 3

x + 2 = 2x - 2x - 4

2 3 3 1 1

3x+4=4x-12x-24

6

3x+4=4x-12x-24

3x-4x+12x=-24-4

11x=-28

x=-28

11

b) 2x+5x+3-4x=4.(2x-8)

2x+5x+3-4x=8x-32

2x+5x-4x-8x=-32-3

7x-12x=-35

-5x=-35 (-1)

5x=35

x=35

5

x=7

espero ter ajudado
