no signs of draggin stuff

so PEMDAS

so wha yyou woul ddo first is see if parenthasees can be simplified
it cannot
so next we do multiply or distribute the 9
9(x+2)=9x+18

so now we have
9x+18=90
then we do subtraction
of 18
9x=72
divide 9
x=8

so order is multiplication then subtraction then division
