Answer:
u = - ( 9-6w)/2
Step-by-step explanation:
to evaluate for u in the expression -2u+6w=9 is simply to look for a way such that we would express u in terms of w and other variables.
solution
-2u+6w=9
-2u = 9 - 6w
divide both sides by the coefficient of u which is -2
-2u/u = 9 - 6w/-2
u = - ( 9-6w)/2
therefore the value of u when rearranged in the equation -2u+6w=9 is evaluated to be equals to
u = - ( 9-6w)/2
