Find the value of x if A=1x+12 and B=3x

Answer 1

To find the value of x, we can set A equal to B and solve for x.

A = B
1x + 12 = 3x

Next, we can subtract 1x from both sides of the equation:

12 = 2x

Now, we divide both sides of the equation by 2 to solve for x:

12/2 = 2x/2
6 = x

Therefore, the value of x is 6.
