Can I get help on 2 and 3?

Hi,

2.

5(3+2x) = 10x - 4

15 + 10x = 10x - 4

10x - 10x = - 4 - 15

0 = -19

In other word there is no solution here, code G

3.

x+5 = (3x+13) / 2

x+5 = (3/2)x + 13/2

x - (3/2)x = 13/2 - 5

x(1-3/2) = 13/2 - 10/2

x(2/2 - 3/2) = 3/2

(-1/2)x = 3/2

x = (3/2) / (-1/2)

x = (3/2) * (-2)

x = (-6/2)

x= -3

code : D

Good Luck :)
