PLEASE HELP. WILL MEDAL ~ Solve. 3y + 15 > –6 A. y > 3 B. y > –7 C. y > 13 D. y > –17
Ok first you need to -15 from both sides
so that would give you 9
then what is 9/3
9 divided by 3?
yep
3
so your answer is A
there is you answer
Thank you.

wouldn't it be? 3y +15 > -6 -15 -15 3y > -21 -------- 3 3 y > -7
what is a negative - a negative
if your subtracting from a negative it means your adding
i keep getting -21
i think you're thinking of multiplication rule for -1 time -1 = 1
subtraction Ex. 6 - 2 = 6 + (-2) = 4 Ex. -6 - -2 = -6 + (+2) = -4 Ex. -6 - 2 = -6 + (-2) = -8 <----- Ex. 6 - -2 = 6 + (+2) = 8 so this would make the problem -21 since -6 - 15 forgive me if im wrong, its been years since i did this
i did a little research http://mathhomeworkanswers.org/49400/what-is-y-in-3y-15-6
Rule of thumb always picture the number line when you add go to the right when you subtract go to the left when you add a minus you are subtracting when you subtract a minus you are "bouncing back" so add go right for this problem 3y + 15 > –6 what @HeatDude has is correct ; y>-7 to check you can always pick a number and plug it in example use a number >-7 choose 2 then 3*2 + 15 = 6 + 15 =21 which is >-6 example use a number <-7 choose -8 then 3*(-8) +15=-24 + 15 which is <-6
yes i was wrong so go ahead and beat me down im sorry
