Question

1. 5x= 20
2. 14x – 30 = 40
3. -10x – 16 = 24
4. 8x – 20 = 52
5. -12x – 18 = 10
por favor ayuda ​

Answer 1

Explicación paso a paso:

1) 5x=20

x=20/5

×=4

2) 14x – 30 = 40

14x= 70

x= 70/14

x=5

3) -10x – 16 = 24

-10x= 40 /(-1)

10x=40

x= 40/10

x=4

4) 8x – 20 = 52

8x=72

x=72/8

x=9

5) -12x – 18 = 10

-12x=28 /(-1)

x= -28/12 simplificar

x= - 14/6 = - 7/3

x= -7/3
