Answer 1

To solve the system of equations, we can use the method of substitution or elimination. Let's use the method of substitution:

1. Solve one of the equations for one variable in terms of the other. Let's solve the second equation for x:

x + y = 2
x = 2 - y

2. Substitute the expression for x into the other equation:

3(2 - y) + y = 3

3. Simplify the equation:

6 - 3y + y = 3
6 - 2y = 3

4. Solve for y:

-2y = 3 - 6
-2y = -3
y = -3 / -2
y = 3/2

5. Substitute the value of y back into the equation for x:

x + y = 2
x + 3/2 = 2
x = 2 - 3/2
x = 4/2 - 3/2
x = 1/2

Therefore, the solution to the system of equations is x = 1/2 and y = 3/2.
