5x 4y 5 7x y 40 What is the ordered pairsolution of the sy

5x+ 4y = -5

-7x + y =40

What is the ordered pair/solution of the system?

The given equations are

5x+ 4y = -5 ... (i)

-7x + y =40 ... (ii)

Multiply (ii) by 4

-28x+4y =160 ... (iii)

Subtract (i) from (iii)

-33x = 165

x = -5

Substitute in (i)

-25+4y = -5

4y =20

or y =5

Hence ordered pair solution = (-5,5)
