Determine the equivalent system for the given system of equations.

4x − 5y = 2
3x − y = 8

4x − 5y = 2
10x − 7y = 18

4x − 5y = 2
3x − 8y = 4

4x − 5y = 2
10x + 3y = 15

4x − 5y = 2
7x + 6y = 10

Thanks guys!

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125
