Question

-4x + 5y = 17
4x + 6y = -6​

Answer 1

x=-3 and y=1

Explanation:

-4x+5y=17 ---------(i)

4x+6y=-6 ----------(ii)

Using elimination method;

Adding both equation:

-4x+4x+5y+6y=17+(-6)

11y= 17-6

11y=11

y=11/11

y=1

substitute y into equation (i) or (ii);

4x+6(1)=-6

4x+6=-6

4x=-6-6

4x=-12

x=-12/4

x=-3
