Answer 2

To solve this system of equations, you can use the method of substitution or elimination. I'll use the elimination method.

Here are your equations:

1. -2x + 3y = 8
2. 4x + 5y = 6

We can eliminate one of the variables by multiplying one or both equations by suitable constants so that the coefficients of either x or y will cancel each other out when added or subtracted. In this case, I'll eliminate x.

First, multiply both sides of equation 1 by 2, so it becomes:

3. -4x + 6y = 16

Now, add equation 2 and equation 3:

(4x + 5y) + (-4x + 6y) = 6 + 16

This simplifies to:

11y = 22

Now, divide both sides by 11 to solve for y:

y = 22 / 11 y = 2

Now that we have the value of y, we can substitute it back into either equation 1 or 2 to solve for x. I'll use equation 1:

-2x + 3(2) = 8

Simplify:

-2x + 6 = 8

Now, subtract 6 from both sides:

-2x = 8 - 6 -2x = 2

Finally, divide both sides by -2 to find x:

x = 2 / (-2) x = -1

So, the solution to the system of equations is:

x = -1 y = 2
