Solve using the multiplication principle
7x <_ 35
the sign is an inequality equal greater or lesser than sign
would I substitute the sign for an equal sign and then divide 35 by 7
x=5
7 x 5= 35
how would I write the solution set? can someone please help me?

7x <_ 35 or
7x ≤ 35 , divide by 7
x ≥ 5
remember that if you multiply or divide by a negative number, the sign of inequality has to be reversed.
