Answer:
x-12≤7
x≤19
Step-by-step explanation:
less than means it comes after
x-12
is at most means less than or equal to
Add 12 to each side
x-12+12≤7+12
X - 12 ≤ 7; X ≤ 19
Using the keywords less than, at most, and 'a number' we can identify the expression.
Now let's solve for x:
x - 12 ≤ 7
+12 +12
X ≤ 19
