Answer 2

2x-5y=7

2x+5y=17

4x = 24

x = 24/4 = 6.

x = 6.

Answer 3

To solve the system of equations:

1. 2x - 5y = 7
2. 2x + 5y = 17

We can use the method of elimination to find the values of x and y.

Add both equations to eliminate y: (2x - 5y) + (2x + 5y) = 7 + 17

Simplify: 4x = 24

Now, isolate x: x = 24 / 4 x = 6

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

2x - 5y = 7

Substitute x = 6:

2(6) - 5y = 7 12 - 5y = 7

Now, isolate y:

-5y = 7 - 12 -5y = -5

Divide by -5:

y = -5 / -5 y = 1

So, the solution to the system of equations is x = 6 and y = 1.
