Question

Resuelve las siguientes ecuaciones
A-) 10x - 10 = 5( x + 2
B-) 5(x + 4) = 3 ( x + 10) -8

Answer 1

Explicación paso a paso:

a. 10x-10=5x+10

x=20/5=4

b. 5x+ 20=3x+30-8

5x+20=3x+22

x= 2/2=1

Answer 2

10x - 10 = 5(x + 2)

10x - 10 = 5x + 10

10x = 5x + 10 + 10

10x = 5x + 20

10x - 5x = 20

5x = 20

x = 20/5

x = 4

5(x + 4) = 3(x + 10) - 8

5x + 20 = 3x + 30 - 8

5x + 20 = 3x + 22

5x + 20 - 22 = 3x

5x - 2 = 3x

5x = 3x + 2

5x - 3x = 2

2x = 2

x = 2/2

x = 1
