Solving Equations Practice Test
The Solving Equations Practice Test is below. There is a total of 7 pages for you to print out. The page numbers are located in the upper right hand corners. Don't worry that it is labeled Ch. 3 Practice Test. Solving equations used to be Ch. 3 in the old book, but now it's your Ch. 2. No biggie. Just ignore the title.
See if you can do all of these problems within an hour and a half. This is what "game time" (test time) will look like next Thursday so make sure you
PRACTICE, PRACTICE, PRACTICE!!!!
If these problems seem difficult to you now during practice, then they will be tough to perform during the "game". That means you have to practice 1000 times harder. If, however, they seem easy to you during practice, then "game" time will be a breeze.
Other than that, have a PG-13 weekend and I will everyone on Tuesday!

# 25:
by + a = z
to solve for y, give yourself directions to the party from y:
1. multiply by b
2. add a
now to get back home to y, you have to do the opposite of the above 2 steps in reverse order:
1. minus a
2. divide by b
by + a = z
by = z - a
y = z - a over b
okay for #29
ay+by-5=10+c
I plus 5 to 10 got 15+c (your first step was right. everything else you did was wrong).
you now have:
ay + by = 15 + c
you should do reverse distributive property on the left hand side to get :
y (a + b) = 15 + c
now divide both sides by (a + b) to get:
y = 15 + c all over a + b
