Question

Solve the inequality –y < –2.

Answer 1

you need to isolate y to solve it. there is no possible way to get an exact value for y since it's an inequality, not an equation (with an equal sign)

so... -y < -2 (take the negative to the other side, this changes the sign of the inequality)
y > 2

Answer 2

wow thank you I get it now

Answer 3

no problem, medal please :)

Answer 4

do you mind answering another question?

Answer 5

sure, ican try

Answer 6

solve the inequality 48<-3x.

Answer 7

isolate y by dividing -1 to both sides.
when you divide or multiply by a negative number, switch the sign.

Answer 8

@gideon737 48<-3x
-16>x

Answer 9

so divide both sides by -3 to isolate x
48<-3x.
(-48/3) < (-3x/-3)
-16 > x (again, the sign flips since you are multiplying/dividing a negative)

Answer 10

thank you @rimshaa and @dalia_lam I just have one last question Which of the following is in the solution set of the inequality –28 < v – 16?

Answer 11

-28 < v -16 (take -16 to the other side, no sing flipping needed since it's just adding/subtracting)

-28+16 < v

-12 < v

Answer 12

thanks! @rimshaa

Answer 13

no problem
