To solve the equation, we need to clarify the expression a bit more, as it is currently not in a standard mathematical format.
Assuming the equation is supposed to be interpreted as:
21x = 3 + 14
First, we simplify the right side:
3 + 14 = 17
Now, the equation looks like this:
21x = 17
Next, we can solve for x by dividing both sides by 21:
x = 17 / 21
To simplify this fraction, we divide both the numerator and the denominator by their greatest common divisor, which is 1 in this case (since 17 is a prime number and does not divide 21). Thus, we keep it as is:
x = 17/21
In decimal form, this would be approximately:
x ≈ 0.8095
So, the solution to the equation is x = 17/21 or approximately x ≈ 0.8095.
