6(2x+5)=-3(-x+2)

Answer 1

Hola! :3

Resolvemos:

1)

-6x+8 = 2x+64

8-64 = 2x+6x

-56 = 8x

-56/8 = x

-7 = x

2)

3y+6 = -30+2y

3y-2y = -30-6

y = -36

3)

2(6+5x)-11 = 71

2(6+5x) = 71+11

2(6+5x) = 82

6+5x = 82/2

6+5x = 41

5x = 41-6

5x = 35

x = 35/5

x = 7

4)

4(8-4n) = 3(n-40)+4

4(8)+4(-4n) = 3(n)+3(-40)+4

32-16n = 3n-120+4

32+120-4 = 3n+16n

148 = 19n

148/19 = n

Espero haberte ayudado :D
