Can someone help with this equation?

You can put this solution on YOUR website! Remember, with all word problems, common words like "is" and "less" stand for mathematic symbols such as = and -
So here is a list of keywords that translate to mathematic symbols (there are more common keywords, but this list should work for this problem):
Keyword(s) | What it really means | Mathematic Symbol or variable |
times, of | Multiplication | * |
plus, more | Addition | + |
minus, less | Subtraction | - |
is, is equal | Equality | = |
a number, some number | Unknown variable | x (note: this is a letter and not the multiplication symbol) |
note: when you say "5 less than 10", you're really saying "take 5 away from 10" or "10 subtract 5" which translates to 10-5. So it is important to reverse the order of the numbers. If you don't, then you'll end up with a completely different number.
So let's look at the sentence:
"Ten plus 6 times a number is equal to 5 less than the number"
Now pick out the keywords:
Ten plus 6 times a number is equal to 5 less than the number
Now replace the underlined keywords with their corresponding symbol or variable (use the table if you are in doubt)
10 + 6 * x = x-5
So our translated equation is
Now let's solve for x
Start with the given equation
Subtract 10 from both sides
Subtract x from both sides
Combine like terms on the left side
Combine like terms on the right side
Divide both sides by 5 to isolate x
Divide

Answer:
So our answer is
So the number is -3
