Question

resolva:

a)4-3x=5-2x
b)5-3x=2x-1
c)5x-4=10-2x
d)8x+2=6x+4

me ajudem por favor

Answer 1

A) 4 - 3x = 5 - 2x
- 3x + 2x = 5 - 4
- x = 1 (-1)
x = - 1

B) 5 - 3x = 2x - 1
- 3x - 2x = - 1 - 5
- 5x = - 6 (-1)
5x = 6
x = 6/5
x = 1,2

C) 5x - 4 = 10 - 2x
5x + 2x = 10 + 4
7x = 14
x = 14/7
x = 2

D) 8x + 2 = 6x + 4
8x - 6x = 4 - 2
2x = 2
x = 2 / 2
x = 1
