If a+b=5 and a-b=3 then b=?
adell [148]

Lets use elimination to solve the system of equations. We do this by adding the two equations terms together.


a + b = 5

a - b = 3

(a + a) + (b + (- b)) = (3 + 5)

2a + 0 = 8

We can then solve this new equation for a.


2a = 8


a = 4


After this, we can plug in the value of a into one of the equations and solve for b.


a + b = 5


4 + b = 5


b = 1


You're correct, the answer is 1.
