Maurice's sister is 7 years younger than her brother. she is years old. which equation and solution represents how old Maurice is?
Let's represent Maurice's age as M. Since Maurice's sister is 7 years younger than him, we can represent her age as M - 7.
Therefore, the equation representing Maurice's age is: M = (M - 7) + 7
By solving the equation, we get:
M = M - 7 + 7
M = M
Since the equation just equalizes for M, there are infinite possible values for M that satisfy the given conditions.
