Solve the system of equations.

3x + y = 3

x + y = 2

When solving system equations, we can use substitution method or elimination. Today I'm using substitution method.

First name the 2 equations.

3x + y = 3 (1)

x + y = 2 (2)

Now pick one equation and express one algebra in forms of the other.

From (2),

x = 2 - y (3)

Now substitute (3) into (1),

3 (2-y) + y = 3

6 - 3y + y = 3

6 - 2y = 3

6 - 3 = 2y

y = 1.5

Now substitute y = 1.5 into (2)

x + 1. 5 = 2

x = 2 - 1.5

x = 0.5

Therefore the answer is x = 0.5 and y = 1.5
