If you get paid a salary, and you want to know the weekly amount of pay, you need to determine the number of weeks in a year. Sure, you might say "But that's 52 weeks". Wrong.

Determine the number of solutions: 6x-2=x+13

Finger [1]

Answer: B) one solution

Reason: if we solve for the sides of the equation by putting like terms together we get that x = 3

There is no solution when the numbers don’t equal each other, take for instance 1 = 2

It has infinite solutions when the numbers are equal to each other like
1 = 1

It has one solution when the x value is equal to something like x = 9

I also worked out the equation on paper, so you could get a more visual way of how I solved it.
