Showing work:

subtract 1 from both sides of a) x = 2-1 =1

b) substract 4 from both sides to get x = 7-4=3
c)substract 7 from both sides to get x = 3-7 = -4

Of course, normally teachers will make you check your work and show it, but these are so trivial i doubt it matters.

dojo, start with harder stuff :DDD

The list would probably be too long, and if Dojo's like me, he just makes it up as he goes along. Very Happy

Dojo, maybe you could allow others to make new topics here so you don't have to do it all by yourself.

Maybe you could allow a select few to post new topics in this forum (hint hint izzy) maybe me too, and pythag is pretty smart.
