Question

elimination method 3x-2y=5 n 5x3y-21=​

Answer 1

Answer:

(1)×3-------9x -6y =15

(2)×2------10x-6y =42

by elimination method,

change the sign for the second expression

we will get

-x=-27

x=27

sub's x=27 in 3x-2y=5,

3(27)-2y=5

81-2y=5

2y=81-5

2y=76

y=38

hence,

x=27

y=38

have a nice day!!!!!!!
