To solve these two equations simultaneously, we can either use substitution or elimination method.
Let's first solve using the substitution method:
From equation 1: a + b = 7=> b = 7 - a
Now substitute this value of b into equation 2:
a + 2(7 - a) = 9a + 14 - 2a = 9
Now, substitute the value of a back into equation 1:5 + b = 7b = 2
Therefore, the solution to the system of equations is:a = 5b = 2
To solve these two equations simultaneously, we can either use substitution or elimination method.
Let's first solve using the substitution method:
From equation 1: a + b = 7
=> b = 7 - a
Now substitute this value of b into equation 2:
a + 2(7 - a) = 9
a = -5a + 14 - 2a = 9
=> a = 5
Now, substitute the value of a back into equation 1:
5 + b = 7
b = 2
Therefore, the solution to the system of equations is:
a = 5
b = 2
