TWO different ways to represent this diagram is

​

y + 3 = 6 OR 3 + y = 6

​

no matter how the order it is written you will solve it the same way​

​

This is a diagram of an addition equation

​

Multiple Choice

What is the first step to solve this equation?

• Subtract y from both sides

• Subtract 3 from both sides

• Divide 3 to both sides

• Divide y to both sides

If the equation looks like this

y + 3 = 6 OR 3 + y = 6

​​

​you will subtract the additional group first!

Multiple Choice

What is the first step to solve this equation?

z + 5 = 100

• Dividing by 5 on both sides

• Multiplying by z on both sides

• Subtracting z on both sides

• Subtracting 5 on both sides

Multiple Choice

What is the first step to solve this equation?

40 + x = 50

• Multiplying 40 to both sides

• Subtracting 40 to both sides

• Dividing 40 to both sides

• Multiplying 40 to both sides

This diagram shows EQUAL GROUPS of the variable and NO additional group.​

​

3x = 6​

​

Multiplication is REPEATED addition!

​Here is an example of a multiplication equation.​

Multiple Choice

What is the first step to solve this equation?

3x = 6

• Subtract 3 to both sides

• Divide 3 to both sides

• Multiply by 3 on both sides

• Add 3 to both sides

The opposite of multiplication is division so we need to divide each side by 3 to figure out the value of x!

​

We need to divide!​

Multiple Choice

What is the first step to solve this equation?

50 = 10x

• Divide both sides by 10

• Divide both sides by 50

• Subtract 10 on both sides

• Multiply by 10 on both sides

Multiple Select

What is the first step to solve this equation?

$$\frac{25}{100}x$$   = 40

• Subtract 25/100 on both sides

• Multiply by 100/25 on both sides

• Divide by 25/100 on both sides

• Add 25/100 to both sides

To divide fractions you must multiply by the reciprocal! ​
