Question

alguien que me ayude a resolver esas ecuaciones porfisss ​

Answer 1

Explicación paso a paso:

-2(3x+2) = 5(x-4)

-6x-4 = 5x-20

-6x - 5x = -20+4

-11x = -16

-11x/11 = -16/11

x= -16/11

2x+3=4x

2x-4x=-3

-2x = -3

-2x/-2 = -3/-2

x= 3/2

2(2x+1)=30

4x + 2 = 30

4x + 2 - 2 = 30-2

4x = 28

4x/4 = 28/4

x = 7
