Question

resolver cada ecuacion de dos maneras diferentes

3(x+2)=12
(12x-8):2=14
(2x-5).4=20

Answer 1

Explicación paso a paso:

3(x+2)=12

1. x+2=12/3

x+2=4

x=2

2. 3x+6=12

3x=6

x=2

(12x-8):2=14

1. 12x-8=28

12x=36

x=3

2. 6x-4=14

6x=18

x=3

(2x-5)×4=20

1. 2x-5=5

2x=10

x=5

2. 8x-20=20

8x=40

x=5
