Answer 3

You have a system of two linear equations:

1. x - 5y = 36
2. -2x - 3y = 32

You can solve this system of equations using either the substitution method or the elimination method. I'll demonstrate the elimination method here:

First, we can multiply the second equation by -1 to make it easier to eliminate one of the variables:

1. x - 5y = 36
2. 2x + 3y = -32

Now, you can add the two equations together to eliminate the x variable:

(1) + (2):

(x - 5y) + (2x + 3y) = 36 - 32

Now, combine like terms:

3x - 2y = 4

Now you have a new equation:

3x - 2y = 4

You can solve this equation for x:

3x = 4 + 2y 3x = 2y + 4 x = (2y + 4)/3

Now that you have the value of x in terms of y, you can substitute this expression into one of the original equations (I'll use equation 1):

x - 5y = 36

Substitute the expression for x:

(2y + 4)/3 - 5y = 36

Now, you can solve for y:

Multiply both sides of the equation by 3 to get rid of the fraction:

2y + 4 - 15y = 108

Combine like terms:

-13y + 4 = 108

Subtract 4 from both sides:

-13y = 108 - 4 -13y = 104

Now, divide by -13 to solve for y:

y = 104 / -13 y = -8

Now that you have found the value of y, you can substitute it back into the expression for x:

x = (2y + 4)/3 x = (2*(-8) + 4)/3 x = (-16 + 4)/3 x = -12/3 x = -4

So, the solution to the system of equations is:

x = -4 y = -8
