7x-6= -20
If you need this solved further, then it would be
x=2
Step-by-step explanation:
a number can be anything, so we represent it with x. 6 less means you subtract six, and seven times a number means 7x. Put this as an equation and you have
7x-6=-20. If you need this solved even more, after applying to both sides, its
x=2.
Hope this helps!
