5y - 13 = 12
With these you always have to DO THE SAME THING to BOTH SIDES OF THE EQUATION.
You are looking for y. So to get rid of that -13, do the opposite. You ADD 13 to both sides of the equation, and you get:
5y - 13 + 13 = 12 +13
Simplify that a bit and it becomes:
5y = 25
Remember you are still looking for the value of y. You have 5 multiplied by y there. Do the opposite. Divide both sides of the equation by 5, and you get:
5y / 5 = 25 / 5
Left hand side: 5 divided by 5 = 1 and 1 x 5 = 5.
Right hand side: 25 / 5 = 5... so your answer is:
y = 53x-4x=12 that means -x equals 12 so x equals -12
6 +6 = 12
False, 12 x 12 equals 143!JOKES! It actually equals 144!hehe!
Neither of the two is correct. It would be 12 inches equals a foot or 144 inches equals 12 feet.

48 divided by 12 equals 4. 48/12 = 4
Well, if 3x equals 12, then x equals 4. And if y equals 3x, then y equals 3 times 4, which is 12. So, y equals 12. Math can be a piece of cake when you break it down like that!
The answer is "FALSE".
If 6a divided by 2 equals 12 then A equals
3x-4x=12 that means -x equals 12 so x equals -12

45 - 12 equals = 33
It equals exactly 12 pounds!
6 +6 = 12

False, 12 x 12 equals 143!JOKES! It actually equals 144!hehe!
12 equals 3x(4) equals 6x(2) equals (12)x1
