You can put this solution on YOUR website! 7+2[3(x+1)-2(3x+1)]
Remember the order of operations. PEMDAS = Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.
This is BODMAS if you are in the UK, Australia, and other countries where parenthesis are called brackets: Brackets, Orders, Division Multiplication, etc.
~~~~~~~~~~~~~~~~~~~~~~~~
Start from the inside:
3(x+1)-2(3x+1) Distribute the 3 and the 2 (Distributive Properties of Multiplication):
3x+3-6x+1 = 4-3x
7+2(4-3x) = 7+8-6x = 15-6x
