Question

5x +3y = 14 2x - 5y = 18 it by cross multiplication.​

Answer 1

Answer:

5x-3y=-14-----------(1)

2x+5y=-18-----------(2)

multiplying (1) by 5 & (2) by 3

25x-15y=-70

6x+15y=-54

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

31x+0=-124 =>31x=-124=>=-124/31=-4=>x=-4

now substituting x=-4 in (2)

2(-4)+5y=-18

-8+5y=-18

5y=-18+8=-10=>5y=-10

y=-10/5=-2

y=-2
