Answer 2

To solve the system of equations:

1. 3x + y = 3
2. 2x - y = 7

You can use one of the common methods, such as substitution or elimination. Let's use the elimination method:

Step 1: Add the two equations to eliminate the variable "y."

(3x + y) + (2x - y) = 3 + 7

Simplify:

5x = 10

Step 2: Solve for "x" by dividing both sides by 5:

x = 10 / 5

x = 2

Step 3: Now that we have the value of "x," we can find "y" by substituting it into one of the original equations. Let's use the first equation:

3x + y = 3

Substitute x = 2:

3(2) + y = 3

6 + y = 3

Step 4: Solve for "y" by isolating it on one side of the equation:

y = 3 - 6

y = -3

So, the solution to the system of equations is x = 2 and y = -3.
