-2x + 4 = 12
Explain what mistake did he make

step one -4 from12 = 8 so -2x=8   divde -2x by -2 to get rid of the -2 and do it to the other side to get -4 so x =-4

Step-by-step explanation:

X=-4

Step-by-step explanation:

-2x + 4 = 12

so what you would do is subtract 4 from itself and 12

4 - 4 = 0

12 - 4 = 8

then we have-

-2x = 8

we then divide 2 from 2 and 8

2 divided by 2 = 0

2 divided by 8 = 4

so x = -4
