Answer: x = 16
Step-by-step explanation: First isolate the x term by subtracting 12 from both sides of the equation and we get 3/4x = 24.
Now, notice that x is being multiplied by a fraction. In this situation, in order to get x by itself, we must multiply both sides of the equation by the reciprocal of that fraction. The reciprocal of a fraction is just that fraction flipped so the reciprocal of 3/4 is just 4/3.
So here, in order to get x by itself, we multiply both sides of the equation by 4/3. On the left, our 4's cancel and our 3's cancel and we are left with x. On the right, our 12 and 3 reduce to 1 and 4 so we have (4)(4) which is 16.
So x = 16.
