Question

How to write in number form and answer 15 more than three times a number is at most 7

Answer 1

at most= less than or equal to= ≤
more than= addition
times= multiplication
x= a number

3x + 15 ≤ 7
subtract 15 from both sides

3x ≤ -8
divide both sides by 3

x ≤ -8/3


CHECK:
3(-8/3) + 15 ≤ 7
threes cancel out
-8 + 15 ≤ 7
7 ≤ 7


ANSWER: x ≤ -8/3

Hope this helps! :)
