Question

me ajudem!!
A) 4 x = - 12
B) 2 x - 5 = x + 1
C) 2 x + 3 = x + 4
D) 5 x + 7 = 4 x + 10
E) 4 x - 10 = 2 x + 2
F) 4 x - 7 = 8 x - 2
G) 2 x + 1 = 4 x + 10​

Answer 1

a) 4x = -12

x = -12/4

x = - 3

b) 2x -5 = x +1

2x - x = 1 +5

x = 6

c) 2x - x = 4 - 3

x = 1

d) 5x -4x = 10 -7

x = 3

e) 4x - 2x = 2 +10

2x = 12

x = 12/2

x= 6

f) 4x - 8x = - 2 +7

- 4x = +5

x = 5/-4

x = - 5/4

g) 2x - 4x = 10 - 1

- 2x = 9

x = 9/-2

x = - 9/2
