Answer:
p - 7 = 42
Step-by-step explanation:
"Less than" might make you think of the < sign, but that's a mistake. The expression 7 < p = 42 makes no sense! In fact, that would say, "7 <u>is</u> less than p and p = 42."
To find 7 less than a number, you subtract 7 from the number. You start with the number, then subtract 7.
p - 7 = 42
Both are functions. Try not to get tripped up on notation of functions. They are they same, just written differently.
f(x) = 3x-10 is the same as 0=3x-10
2x+7y=28 is the same as 2x+7y-28=0
Just one will give you a line and the other will give you a circle. If you are ever unsure, plug them into a graphing calculator and see what you get back.

5(-2) - 2(3) / 2(5-3)
5-3 = 2
5(-2) - 2(3) / 2(2)
5 * -2 = -10
-10 - 2(3) / 2(2)
2*3 = 6
-10 - 6 / 2(2)
-10 - 6 / 4
6 / 4 = 1.5
-10 - 1.5 = -11.5
