What operation is happening in this problem? 

5x = 40

Multiplication (ab)

125

What is the INVERSE operation of this problem:

5x = 40

Division (a/b)

125

Find the value of x for this problem:

5x = 40

Divide by 5 on both sides

x = 8

125

If x = 8, then show that 5x = 40.

5(8) = 40

40 = 40

250

What operation is happening in this problem: 

49 = x - 6

Subtraction ( a - b )

250

What is the INVERSE operation of this problem:

49 = x - 6

Addition ( + )
250

Find the value of x for this problem:

49 = x - 6

Add 6 to both sides

x = 55

250
If x = 55, then show that 49 = x - 6.

49 = (55) - 6

49 = 49

375
What operations are happening in this problem: 

4m + 8 = -88


Multiplication (ab) 

Addition (a + b)

375

What are the INVERSE operations of this problem?

4m + 8 = -88


Subtraction ( - )

Division ( a/b)


375

Find the value of m for this problem: 

4m + 8 = -88

Subtract 8 first, then divide by 4 

m = -24

375

If m = -24, then show that 4m + 8 = -88

4(-24) + 8 = -88

-96 + 8 = -88

-88 = -88

500

What operations are happening in this problem?

-5m + 7 = 42

Multiplication (ab)

Addition (a + b)

500

What is the INVERSE operation of this problem:

- 5m + 7 = 42

Subtraction ( - )

Division (a/b)

500

Find the value of m for this problem:

- 5m + 7 = 42

Subtract 7 first, then divide by -5

m = -7

500

If m = -7, then show that -5m + 7 = 42

-5(-7) + 7 = 42

35 + 7 = 42

42 = 42
