Are there any parentheses in this equation? that would determine what you do first.
if it is (7+2)•4 your answer is 36.
if it is 7+2•4, then your answer would become 7+8, which is 15.
First you distributive property:
3x-15=9
Add 15
3x=24
Divide
x=8
To find the sum, add. To find the difference, subtract. It's simple terminology in mathematics. Hope I helped!
