Question

ache a raiz de cada equaçaõ:
a) 3-2x=17-4x
b) x-1=7-2x
c)x+1+2x=1-3x

Answer 1

a) 3 - 2x = 17 - 4x
- 2x + 4x = 17 - 3
2x = 14
x = 14/2
x = 7

b) x - 1 = 7 - 2x
x + 2x = 7 + 1
3x = 8
x = 8/3

c) x + 1 + 2x = 1 - 3x
x + 2x + 3x = 1 - 1
6x = 0
x = 0

Answer 2

a) 3-2X=17-4X
-2x+4X=17-3
2X=14
X=7
b)X-1=7-2X
X+2X=7+1
3X=8
X=8/3
c)X+1+2X=1-3x
X+3X+2X=1-1
6X=0
X=0/0
X=0
