Now, I am going to show you how to solve equations with brackets.
Let's say 6(x+7)=54. There are 2 ways to solve this equation. I am going to tell you the first way.
6( ) means 6*( ), so opposite operation of multiplication is division. The equation is 6(x+7)=54 then you need to divide by 6 and you also need to divide y 6 to where 54 is, so 54 6=9. Then there is x+7=9 left. 9-7=2. The x equals 2.
