Question

equação do 1 grau 2x-5=x+1

Answer 1

OI

a) 6x = 2x + 16

6x - 2x = 16

4x = 16

x = 16/4

x = 4

b) 2x - 5 = x + 1

2x - x = 1 + 5

x = 6

c) 2x + 3 = x + 4

2x - x = 4 - 3

x = 1

d) 5x + 7 = 4x + 10

5x - 4x = 10 - 7

x = 3

e) 4x - 10 = 2x + 2

4x - 2x = 2 + 10

2x = 12

x = 12/2

x = 6

f) 3x - 4 = 2x + 8

3x - 2x = 8 + 4

x = 12

g) 7x - 2 + 4 = 10 + 5x

7x - 5x = 10 + 2 - 4

2x = 8

x = 8/2

x = 4

Boas lições.
