Answer:
22?
Step-by-step explanation:
I sorry if my answer is wrong.
Solve for the variable y (move the x to the right of equal with changed sign)
M is the coefficient before the x and b is the known number
-3y = -12 - 6x
Since the y can't be negative, multiply every term for -1, therefore change their sign
3y = 6x + 12
To find y, divide both terms for 3

y = 2x+4
Therefore your answer is
y = 2x+4
Answer:
A batch is 12 so if you have two batches it would be 24 and so on.
Step-by-step explanation:
This might be wrong, but you need to get x be itself on the left side and then after you do that, the x on both sides will cancel. Whenever you try to subtract one x from the other it will cancel them. So technically that's all you can do.
