Question

me ajudem
2x+1=9


7x-3=3x+13


100x=300


2x=26

Answer 1

a) 2x + 1 = 9
2x = 9-1
2x = 8
x = 8/2

x = 4



b) 7x -3 = 3x + 13
7x-3x = 13 + 3
4x = 16
x = 16/4

x = 4



c) 100x = 300
x = 300/100

x = 3



d) 2x = 26
x = 26/2

x = 13

Answer 2

2x + 1 = 9
2x + 1 - 9 = 0
2x - 8 = 0
2x = 8
x = 8 / 2
x = 4

7x - 3 = 3x + 13
7x - 3x - 3 - 13 = 0
4x - 16 = 0
4x = 16
x = 16 / 4
x = 4

100x = 300
x = 300 / 100
x = 3

2x = 26
x = 26 / 2
x = 13

Espero ter ajudado. Valeu!
