The answer is -47-10w=-9w-40-3w bc the equation above equals 7/2 and this equation does too first combine like terms -47-10w=(-9w+3w)+40 which gives you -10w-47=-12w-40 then Add 12w to both sides which gives you 2w-47=-40 and then Add 47 to both sides and gives you 2w=7 and then divide 2 in both sides and gives you 7/2
