Question

c) 3(2x - 3) + 2(x+1)= 3x + 18
d) 2x + 3(x - 5) = 4x + 9
e) 2(x + 1) - 3(2x - 5) = 6x - 3
1) 3x - 5=x-2
8) 3x - 5= 13
h) 3x + 5 = 2
1)x-(2x - 1) = 23
D) 2x -(x-1)=3-(x - 3)

eu preciso pra jaaa pfv

Answer 1

Resposta:

) 3(2x – 3) + 2(x + 1) = 3x + 18 b) 2x + 3(x – 5) = 4x + 9

6x-9+2x+2=3x+18 2x+3x-15=4x+9

8x-7=3x+18 5x-15=4x+9

8x-3x=18+7 5x-4x=9+15

5x=25 x=24

x=25/5

x=5

c)2(x + 1) – 3(2x – 5) = 6x – 3 d) 3x – 5 = x – 2

2x+2-6x+15=6x-3 3x-x=-2+5

-4x+17=6x-3 2x=3

-4x-6x=-3-17 x=3/2 ou 1,5

-10x=-20 (-1)

10x=20

x=20/10

x=2
