Answer:
A. Equation 1: x + y = 18
Equation 2: x + 2y = 25
B. The lesser number is 7 and the greater number is 11
Step-by-step explanation:
We come up with two equations with the information:
Equation 1: x + y = 18
We solve the equation by substituting x (which is in terms of y):
x = 18 - y
(18 - y) + 2y = 25
y = 7
Now we substitute y into Equation 1:
x + 7 = 18
x = 11
