Lesson 35

Az-3(7)=3

This problem has parentheses. The first thing you do is multiply to remove them.

Problem A: 4Z - 3 (7) = 3

- What numbers are you multiplying?

- What would that be?

4z - 3(7) = 3

4z - 21 = 3

Is anything added or subtracted?

How are we going to get that moved to the other side?

Multiple Choice

What would be 3 + 2 1

• 24

• 23

4z = 24

Next Step..

How are we going to get z by itself? We do the opposite

Multiple Choice

24 divided by 4 is?

So z equals...

• 4

• 6

• 12

8 (4) = 20 + 3p

 $\frac{3}{2}\ \left(5\right)\ -\ \frac{3}{2}\ =\ 6j$  

There are 15 red balls for every 46 yellow balls. If there are 60 red balls, how many yellow balls are there?

What does the problem ask?

*You will need 2 numbers for that name*

What is the other name used in the problem?

What 2 letters would you need for this name?

-20 + 56 =

+3 - 27 =

 $-\frac{3}{9}-\frac{5}{9}=$  

For each sentence, you'll write an equation with letters.
