http://prntscr.com/d5cgal I'm gonna try and solve it first. Hold on!
first is the x/9 so first we do x * 9 and then do -3 * 9
first of all, you have an expression of x, then subtract 1 so you want to get the expression on its own so you have |dw:1478744143911:dw| so first get rid of the -1
what is the opposite to subtract
ooook i thought we're following order of operation here or something haha ok so we add 1 to -3
that is correct!, then you will do the step you said, that is, multiply by 9
so -2 then -2 * 9 = -18
so x = -18
:/
that is correct well done!
you can keep the rest of your questions in this thread, so you don't need to keep makign new questions
have a go at the next question and i will correct you if you do something wrong
