Question

I need help with finding the x and y how would you solve;
2x+3y=4
4x+6y=8

Answer 1

by elimination u subtract the second term from the first term ( remember that when u subtract all the signs change to the opposite)

Answer 2

Multiply the first equation by -2.
-2(2x+3y=4)
4x+6y=8

-4x - 6y = -8
4x + 6y = 8
0 = 0
THis is an identity outcome. Identity outcomes mean infinitely many solutions.
