Question

B 3(x-2)=2x-4



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


D 3(x-1) -7=15

E 7(x-4)= 2x-3

F 3(x-2)=4(3-x)​

Answer 1

Resposta:

b) 3(x-2)=2x-4

3x - 6 = 2x - 4

x = 2

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

2x - 2 = 3x + 4

-x = 6

x = -6

d) 3(x-1) -7=15

3x - 3 - 7 = 15

3x = 25

x = 25/3

e) 7(x-4)= 2x-3

7x - 28 = 2x - 3

5x = 25

x = 5

f) 3(x-2)=4(3-x)

3x - 6 = 12 - 4x

-x = 18

x = -18
