To solve the equation where the quantity of x plus 20 over 2 equals 3x, we can start by expressing this mathematically:
We have:
(x + 20) / 2 = 3x
To eliminate the fraction, we can multiply both sides of the equation by 2:
x + 20 = 6x
Next, we want to isolate x on one side of the equation. To do this, we will subtract x from both sides:
20 = 6x – x
This simplifies to:
20 = 5x
Now, to solve for x, we divide both sides by 5:
x = 20 / 5
This simplifies to:
x = 4
So, the solution to the equation is:
x = 4
To double-check our work, we can substitute x back into the original equation:
(4 + 20) / 2 = 3 * 4
This gives us:
(24) / 2 = 12
Which is:
12 = 12
Since both sides are equal, our solution is verified. The solution to the equation is indeed:
x = 4
