1.)­ 3x + 5y = 15 2.) 2x ­ 4y = 2 3.)18x + 12y = 24
­2x ­ 4y = 6 9x ­ 15y = ­45 3x + 2y = 6

1). Answer x= -5/3 y + 5

2.)  x=2y+1

3.)x=−2/3y+4/3

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above

step-by-step explanation:

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong
