Answer 2

To solve the system of equations:

8x + y = -6
-2x + 5y = 12

There are multiple methods to solve this system of equations. Here, I'll demonstrate how to solve it using the substitution method:

Step 1: Solve one equation for one variable in terms of the other variable. Let's solve the first equation for y: 8x + y = -6 y = -8x - 6

Step 2: Substitute the expression for y from Step 1 into the second equation: -2x + 5(-8x - 6) = 12

Step 3: Simplify and solve for x: -2x - 40x - 30 = 12 -42x - 30 = 12 -42x = 12 + 30 -42x = 42 x = -1

Step 4: Substitute the value of x into one of the original equations to solve for y. Let's use the first equation: 8x + y = -6 8(-1) + y = -6 -8 + y = -6 y = -6 + 8 y = 2

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