Question

16x+10y=18 15x+10y=20 by elimination method​

Answer 1

Answer:

X=-2 and Y = -5

Step-by-step explanation:

u can get the solution by eliminating x also....but here eliminating Y is easy

Answer 2

,

$solution \\ \:16x+10y=18 \: and \: 15x+10y=20$

subracting eqn I from ii

16x+10y=18

15x+10y=20

- + -

x = - 2

Substituting value of x in eqn I

16×(-2)+10y=18

so y = 5

hence, x= -2 and y= 5
