yes
(1) x+y=15(2) 4x+3y=38From (1) one gets x=15 -y, put into(2)4(15-y)+3y=3860-4y+3y=3860-y=38y=22 then x=15-y=-7(-7,22) is the solution
-2x plus 3y equals 1
2x-11
That would depend on the plus or minus value of 3y or maybe an equality is missing none of which have been given.

it is equal to 6y plus y
12y+3=9y-15 3y=-18 y=-6
If y + 3y + 10 = 70, then 4y + 10 = 70, and 4y = 60. We then find that y = 60/4 = 15.
yes
80 = 3y + 2y + 4 + 1 75 = 5y 15 = y y = 15
OK, so-3y + 15 - y = 39-3y + 15 - 15 - y = 39 - 15-3y -y = 24-4y = 24-y = 6y= -6.Hope this helps!
3y+5=y-25 2y=-30 y= -15

3y + 2y + 4 + 1 = 805y + 5 = 805y = 75y = 15
