Answer 1

The system of equations is:

2x + 5y = 320 3x - 2y = 100

To solve for x and y, we can use the method of elimination:

Multiply the first equation by 3 and the second equation by -2:

6x + 15y = 960 -6x + 4y = -200

Add the two equations:

19y = 760

Divide both sides by 19:

y = 40

Substitute y = 40 into either of the original equations to solve for x:

2x + 5y = 320

2x + 5(40) = 320

2x + 200 = 320

2x = 120

x = 60

Therefore, the solution to the system of equations is x = 60 and y = 40.
