Thanks though

Answer 5

30=(x+3)+(x+3)+x

The ( ) don't matter because it is addition, so we can just get rid of those

30=x+3+x+3+x

Answer 6

So its 30=(x+3)+(x+3)+x -----> 30=4x+4x+x ------->30= 9x -------> x=3.3

Answer 7

30=x+3+x+3+x

Combining like terms

30 = 3x + 6

Answer 8

You are allowed to subtract, add, multiply, divide anything from both sides to simplify the equation.

We want to get x by itself.

30 - 6 = 3x + 6 - 6

24 = 3x

divide both sides by 3

x = 8
