Let:

Maggies age = M

Brothers age = B

From the problem develop 2 equations:

B = 2M - 4 Equation 1

M + B = 11 Equation 2

Solve Eq. 2 for B to get: B = 11 - M then substitute into Eq. 1.

11 - M = 2M - 4

-3M = -15

M = 5 Maggie is 5 years old!

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
