what you have to do is get the x to be on its own. So we need to get rid of the 4. Since it's a fraction and fractions are division, you need to multiply both sides by 4. The reason as to why you multiply is because multiplication is the opposite if division. By multiplying both sides you get rid of the four and you are left with:
x>84
Again, let me know if you still need help.

Step-by-step explanation:
Let's call "x" to the number we are looking for.
Now, the problem states that "5 more than the quotient of a number and 8 is 42". This means that this number is being divided by 8, it's also being additioned 5 and the final result is 42. Therefore, the expression of this operations on this number is the following:
. Let's solve the equation to find x.
1. Write the expression.
2. Substract 5 from both sides and simplify.
3. Multiply 8 on both sides and simplify.
<u>We have found our number, it's 296!</u>
