Question

Solve for x and y: 149x-330y= -511; -330x+149y= -32.

Answer 1

Answer:

X=1, Y=2

Step-by-step explanation:

149x-330y=-511 -------(1)

-330x+149y=-32 ------(2)

330*(1) and 149(2)

49170x- 108900 y=-168630

-49170x+22201 y=-4768

------------------------------------

                -86699 y=-173398

           y=173398/86699

          y=2

substitute y value in eq 2

-330x+149y=-32

-330x+149(2)=-32

-330x+298=-32

-330x=-32-298

-330x=-330

x=-330/-330

x=1

lets check it here

substutite x,y values in any equation

-330x+149y=-32

-330(1)+149(2)=-32

-330+298=-32

-330=-32-298

-330=-330

330=330

both sides are equal
