The difference between a number and 5, when multiplied by 3 is 36. What is the number?

Respuesta :

36+(5×3)
5×3=15
36+15=x
x=51
Set up an equation. 3(x-5)=36 Distribute the parentheses. 3x-15=36 Do inverse operations to isolate the variable. (-15+15=0) and (36-15=21) 3x=21 Do the inverse operations again. (3÷3=1) and (21÷3=7) SOLUTION: x=7
