Question

me ayudan por favor ​

Answer 1

Respuesta:

1) x = 95
2) x = 200
3) x = 16
4) x = 7
5) x = 2
6) x = 4
7) x = 24

Explicación paso a paso:

1) x + 5 = 100
x = 100 - 5
x=95

2) x - 80 = 120
x = 120 + 80
x = 200

3) 5x = 80
x = 80/5
x = 16

4) 4x + 3 = 31
4x = 31 - 3
4x = 28
x = 28/4
x = 7

5) 7x + 12 = 2x + 22
7x - 2x = 22 - 12
5x = 10
x = 10/5
x = 2

6) 9x + 5 = 3x + 29
9x - 3x = 29 - 5
6x = 24
x = 24/6
x= 4

7) x/3 = 8
x = 8(3) ó x = 8 x 3
x = 24
