CORRECTION ON PROBLEM 1 OF TUESDAY'S BELL RINGER: 10-7-14
In the equation 25x/7 -7x = 12, I needed to multiply EACH term of the equation by 7 to eliminate the denominator. That means it would look like: 25x-49x = 84. The solution is -21/6.
On your test, you may see an equation like this : 25x/5 - 7 = 12. In this case, you have TWO choices: you can reduce 25x/5 to 5x and solve OR multiply EACH term by 5 and solve.
If you have any questions, ask David.
