Question

How do I fine x in this problem. 4x+3y=12

Answer 1

Answer:

Answer: It's relatively easy to find x in this problem. 4x+3y=12 means that the expression 3y needs to be 12 too, which gives us 12-6 or 6. That number divided by 4 is 2, so x=2! Congrats, you've found x!

Step-by-step explanation:

One way of solving this problem is to remove the parentheses all together and write the equation as 8x+6y = 54. Subtracting 54 from both sides would give us -8x + 6y = 18. The key point here is that when subtracting a negative number, we have to borrow one from our variable so instead our answer becomes (-8)x-6(y)=-54.

Answer 2

Ok so basically you have to get just the x on one side so you subtract 3y from both sides first to make it 4x=-3y+12 and then you can just divide by 4 on all 3 parts of the equation to get x=-3/4y+3
