3x - 7 ≤ 9
"Seven less than" means that you subtract seven from the answer.
"Three times a number" means that you multiply it.
"At most" means that this is the greatest number that it can be, which is, in this case, 9.
To solve this, you apply the principle rules of algebra to determine x.
3x ≤ 9 + 7
3x ≤ 16
x ≤ 16/3
So the problem is: Solve: 4x2 - x = 3
Answer = 7 - 3n
4/7
The real answer is n-7
3x + 7
So the problem is: Solve: 4x2 - x = 3

Three times a number is 10 less five times the number can be put in the form of an equation that looks like this: 3x = 5x-10. Now just solve for x...
3n+12=Answers may vary.
4/7
This is an algebraic expression. It can be written as 3(2x + 4)
3n-7
The real answer is n-7
3x + 7
