Germany and Austria have a total of 25 states. Germany has 7 more states than Austria has. Create 2 equations.
Let g be the number of German states. Let a be the number of Austrian states. We're given two equations:
a + (a + 7) = 25
Combine like terms:
2a + 7 = 25
To solve for a, we type this equation into our search engine and we get:
a = 9
To solve for g, we plug in a = 9 into equation (2):
g = 9 + 7
g = 16
Let g be the number of German states. Let a be the number of Austrian states. We're given two equations:
- a + g = 25
- g = a + 7
a + (a + 7) = 25
Combine like terms:
2a + 7 = 25
To solve for a, we type this equation into our search engine and we get:
a = 9
To solve for g, we plug in a = 9 into equation (2):
g = 9 + 7
g = 16
