gente a ordem das letras estão incorretas mais as questoes nao​

Answer 1

e) -3/4 - x) = 7x-(1-x)

(não entendi)

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

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

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

x=7

i) 5+X=-7 + 8x

x-8x=-7-5

-7x=-12

x=-12/7

k) 5x - 91 = 4x - 77

5x-4x=-77+91

x=14

m) 7x + 1 = 3x +2

7x-3x=2-1

4x=1

x=4/1

x=4

f) 3x + 1 = 2x

3x-2x=-1

x=-1

h) 5x-1=2-X

5x+x=2+1

6x=3

x=6/3

x=2

j) 2(1 - 5y) +36-1-y) - 4(-7 + 2y) = -y

(não entendi esse)

L) 1-3x = 17 - 4x

1-17=-4x+3x

-16=-x

-x=-16 (-1)

x=16

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

3x+9-1=2

3x=2-9+1

3x=-7+1

3x=-6

x=-6/3

x=-2
