The product of a and 6 is 30

• a - 6 = 30

• 6 + 30 = a

• 6 + a = 30

• 6a = 30

When c is added to d, the result is 34

• cd = 34

• 34 + c = d

• c - d = 34

• c + d = 34

My age is n, my son's age is j. When we add them together we get a result of 75

• n + j = 75

• n x j = 75

• 75 + n = j

• j/n = 75

The time it takes me to get to school is m minutes. It takes me 15 minutes longer to get home. My total time driving each day is 55 minutes.

• 2 x 15 + m = 55

• m + 15 = 55

• m + m + 15 = 55

• 55 - m = 15

The difference between 5 times a number and 3 is 12.

• 3h - 5 = 12

• 5h - 12 = 3

• 5h - 3 = 12

• 12h - 3 = 3

• F
• G
• H
• J

Use the table of values of a linear relationship to create an equations to represent the relationship.

Your answer should look like this:

y=8x-3 (this is not the answer, it is an example)

A scuba diver dove 16 ft to an elevation of -50 ft. What was her elevation before the dive? Which equation matches the scenario?

• x - 1/6 = 50

• x - 16 = -50

• 1/6 x = 50

• -50 = 16x

The sum of d and 12 gives an answer of 15

• d÷ 12 = 15

• d + 12 = 15

• 12d = 15

• 15 + 12 = d
