Question

Whats 20 y-3=17 please help

Answer 1

y=1 which when you add 3 to both sides since its a negative normally you will subtract it but when its a negative you add it well anyway you will get 20y-20 so y =1

Answer 2

y would equal 1 because if you take out the y you get the same answer and when you multiply a number times 1 you get the number that is not 1 so replace that y with 1
