Before we begin, lets review the ORDER of OPERATIONS...

What do we look for FIRST when we are given an equation with 2 operations?

Open Ended

What do we look for second?

Open Ended

What do we look for last?

(N x2) + 3 = Y

When N = 2, Y = ____

(N x2) + 3 = Y

Y = 7

Open Ended

In the equation (N x2) + 3 = Y, N= 2.

How did we know Y = 7?

(R +7) x 3 = S

When R = 3, what is S?

Open Ended

(R+7) x3 =S

When R = 3, what is S?

(Z + 3) x 2 = Y

When Z = 2, Y = _______

Open Ended

(Z + 3) x 2 = Y

When Z = 2, Y = _______

Open Ended

4 + (G x3) = M

When G=3, what is M?

Open Ended

2 + (n x7) = P

When N is 1, what is P?

Open Ended
