This PowerPoint presentation covers solving simple one-step equations, proportions, and translating word problems into algebraic equations for a 6th grade math class. It includes examples of each type of problem, showing the step-by-step work and explanations of how to arrive at the solutions. Students are guided on isolating variables, applying the same operations to both sides of an equation, setting up proportions, and determining which parts of a word problem correspond to different parts of an algebraic equation. The presentation also advertises e-book versions of math materials for 4th and 6th grades that are available at low cost on various platforms.

3. Problem 1) What value of x makes the equation
below true?
7 + x = 84
A. 12
B. 77
C. 83
D. 91
Solve simple one-step equations using basic wholenumber facts

4. How to solve
There are 2 basic rules to a problem like this.
Isolate the unknown on one side of the equal sign.
Whatever action you perform must be performed on both
sides of the equal sign.
7 + x = 84
Subtract 7 from both sides to isolate x
7 + x – 7 = 84 – 7
x = 77
The correct answer is Choice B, 77

5. Solve simple proportions within context
Problem 2) Guafi selects 15 pieces of fruit. If 3 out of 5 of
these fruit are bananas, b, how many bananas does Guafi
select?
A. 3
B. 9
C. 13
D. 25

6. How to solve
Facts provided
There are 15 total pieces of fruit
There are 3 bananas for every 5 pieces of fruit
Write a formula that expresses those two statements
15 pieces of fruit, the bananas plus the other fruit, when 3
out of every 5 fruit is a banana.
G-Zibo Tip – In a word problem, the word “is” means equals in the
formula
15 (3/5) = b

7. How to solve
There are 2 basic rules to a problem like this.
Isolate the unknown on one side of the equal sign. In this case it already is.
Whatever action you perform must be performed on both sides of the equal sign.
15 (3/5) = b
Simplify the left side
Multiply 3/5 times 15
3 x 15 = b
5
45 = b
5
9=b
Choice B is the correct answer

8. Translate two-step verbal sentences into
algebraic equations
Problem 3) What algebraic equation represents “three times
the difference of a number, x, and nine equals fifteen”?
A. 9x -3 = 15
B. 3(9) – x = 15
C. 9 – 3x = 15
D. 3(x – 9) = 15

9. How to solve
The statement gives 3 times the difference of x and 9
3(x – 9) equals 15
the word “equals” determines where the equal sign goes,
15 on one side,
everything else on the other
3(x -9) = 15
Choice D is the correct answer
