Opening Exercise:

Solve 10m + 6n = 12 for m

𝑚 =𝑥 + 𝑛

𝑝

Solve the following for x

Now solve for p

Jenn was given the following formula and asked to solve for a in terms of

𝑥 =5𝑏𝑐

𝑎 What should be the first step?

What’s the goal?

What if a was squared (𝑎2), what would be the additional step?

If you were given this equation, how could it be written with parenthesis?6𝑥 − 6 = 12

Use the distributive property to get rid of the parenthesis:5 𝑥 − 3 = 12

5(𝑥) + 5 −3 = 12

5𝑥 − 15 = 12

𝑓𝑥 − 𝑔𝑥 = ℎ

What are some things you notice?

If asked to solve for x, what might be a road block you could hit?

3ab – 2bc = 12 solve for b

qx + 2x = r Solve for x d = f + fx solve for f

–3(x + n) = x solve for x

The formula for the sum of the degree measures of the interior angles of a polygon is 𝑆 = 180(𝑛 − 2).Solve for n, the number of sides of the polygon, in terms of S.

What’s the question asking?

4k + mn = n – 3; n

Your turn!!

–3(m – 2n) = 5m solve for m 3ab – 2bc = 12c solve for c
