Question

This is due today and it would be awesome if someone could do one of these problems so I can see how to do them thanks :)

Answer 1

7x+15=12x+5
Step #1 Subtract 12 from both 7x and 12x on the left and on the right. This is because we only want one x, and combining like terms is not an option therefore we must eliminate.
7x+15= 12x+5
-12 -12
-5x+15=5
Step #2 subtract 15 from both sides.
-5x+15=5
-15 -15
-5x=-10
Step #3 Divided both sides by coefficient which in this case is -5. We want x by itself
x=2

Really hope this made sense. I can help with other problems if you’ll like
