Answer 2

To solve the system of equations:

2x + y = 5 3x + 2y = 12

There are several methods to solve this system, including substitution, elimination, or matrix methods. Let's use the substitution method:

Step 1: Solve the first equation for x in terms of y. 2x + y = 5 2x = 5 - y x = (5 - y)/2

Step 2: Substitute the value of x in the second equation. 3x + 2y = 12 3((5 - y)/2) + 2y = 12 (15 - 3y + 4y)/2 = 12 (15 + y)/2 = 12 15 + y = 24 y = 24 - 15 y = 9

Step 3: Substitute the value of y back into the first equation to solve for x. 2x + y = 5 2x + 9 = 5 2x = 5 - 9 2x = -4 x = -4/2 x = -2

Therefore, the solution to the system of equations is x = -2 and y = 9.
