Question

1) Resolva as equações do 1° grau
4x – 72 = 2x – 8
6m – 7 = 12 – 3m
x - 35 = 155
x + 40 + 2x = 84
5x - 35 = 100 + 15 - 2x
2x - 3 = 25
4x + 40 = 2x + 125
4x -22 = 40 + 2x
m + 4 – 3m = 4 + 12m

Answer 1

4x - 72 = 2x - 8

2x = 64

x = 32

___

6m - 7 = 12 - 3m

9m = 19

m = 19/9

___

x - 35 = 155

x = 190

___

x + 40 + 2x = 84

3x = 44

x = 44/3

___

5x - 35 = 100 + 15 - 2x

7x = 150

x = 150/7

___

2x - 3 = 25

2x = 28

x = 14

___

4x + 40 = 2x + 125

2x = 85

x = 85/2

___

4x - 22 = 40 + 2x

2x = 62

x = 31

___

m + 4 - 3m = 4 + 12m

- 14m = 0

m = 0
