A) 2(×-3)=×+2
B) 3(×-4=2(×+1)
C) 4(×-2)+2(×-1)=3(×+2)
Me ajudem

Answer 1

a)

2(x - 3) = x + 2

2x - 6 = x + 2

2x - x = 2 + 6

x = 8

b)

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

3x - 12 = 2x + 2

3x - 2x = 2 + 12

x = 14

c)

4(x - 2) + 2(x - 1) = 3(x + 2)

4x - 8 + 2x - 2 = 3x + 6

6x - 10 = 3x + 6

6x - 3x = 6 + 10

3x = 16

x = 16 / 3
