Answer:

x=6

Explanation:

2x-5=7

add 5 to both sides

so the -5 cancels out on this side because -5+5=0

on the other side 7+5=12

which means:

2x=12

to get rid of the 2 we need to divided each side by 2

so...

x=6 as 12 divided by 2 is 6 and 2x divided by 2 is just x

this leaves us with x=6
