Question

10-10 = 5(x + 2)
4 (x+5)=2x + 34
2 ( 1+2x) = 10
-2 (3x - 2) = -2
5 (x + 6) = 6 (x + 4)+1
alguien me puede ayudar a sacar el resultado de estás operaciónes ​

Answer 1

Explicación paso a paso:

10×10 = 5(x + 2)

100 = 5x + 10

100 - 10 = 5x

90 = 5x

90/5 = x

18 = x

4 (x+5)=2x + 34

4x + 20 = 2x + 34

4x -2x = 34 - 20

2x = 14

x = 14/2

x = 7

-2 (3x - 2) = -2

-6x + 4 = -2

-6x = -2 + 4

-6x = 2

x = 2 /6 2÷2=1 6÷2=3

-x = 1/3

x = -1/3

5 (x + 6) = 6 (x + 4)+1

5x + 30 = 6x + 24 + 1

5x - 6x = 24 - 30 + 1

-x = -5

x = 5
