Answer»

ong>Step-by-step explanation:

ELIMINATION METHOD :- MULTIPLY 1ST equation by 2 and 2nd equation by 5 We GET

10x+6y=70

10x+20y=140 by solving we get

Y=5 and X=4

Now BY SUBSTITUTION METHOD:--

Put x =35-3y/5 from 1st equation in 2nd equation

we get

1/5(70-6y )+4y=28

by solving we get

X=4 and Y=5
