Alright, darling, let's get down to business. To solve this little math puzzle, you just need to get all the y's on one side and the numbers on the other. So, subtract 4y from both sides, add 3.2 to both sides, and voila, you'll find y equals 2.2. Easy peasy lemon squeezy.
No.

The question is not quite clear, do you mean -6x+3y = -18 and -10+5y = -30? If so then the solution is: -10+5y= -30 5y = -30+10 5y = -20 y = -4 Substitute the value of y into the equation -6x+3y = -18: Answer: x = 1 and y = -4

8 + 5y = 18 Therefore, 5y = 10 y = 10/5 y = 2
No.

4y + 10 = -18 4y = -28 y = -7

x=(-5y-1)/3
5y + 7 = 25y = -5y = -1
no
-2 = 3y-18-5y 16=3y-5y 16=-2y y=-8
