Help in algebra 1?? solving equalities?

-2x < 6
x > 6/(-2)
x > -3

1. 2n/8 = 3 n = 4*3 n = 12 2. 1/4 = 9 rewrite it! 3. -x/5 = -12 x = 12*5 = 60 4. 2/7 (x) = 28 2*x = 28*7 x = 14*7 x = 98 5. 2x/16 = 23 x = 8*23 x = 184

- 6 < 2x

- 3 < x

x > - 3

Okay, just so that you know, this is called an inequality. And, to solve it, this is what you would do:

-2x < 6
1) Divide each side of the inequality sign by -2 so that you are left with only x on the left.
-2x/-2=x, 6/-2=-3; x < -3
2) Flip the sign of the inequality (this is because you always have to flip the inequality sign when dividing or multiplying by a negative number).
x > -3

I really hope this helps you! Still confused about this type of problem (or really anything, for that matter)? Talk to your teacher. (S)he will be glad to give you the extra help that you need.

Note, this is called an inequality.

-2x < 6

x > 6/-2 Note that we have had to change < to > because we have divided both sides by -2.

x > -3

-2x < 6
-2x/(-2) > 6/(-2) = - 3
x > -3
When dividing or multiplying by a negative number, switch the inequality.

Well first you have to divide both sides by negative 2, which cancels out the coefficiant of the x and gives you x<-3, but since you divided by a negative you flip the sign, giving you x>-3. Is that understandable?

-2x < 6

-2x divided by -2 < 6 divided by -2

x > -3 because when you divide or multiply by a negative number you have to switch the sign.

get it? :)

-2 x < 6
(-2 x < 6)/-2 (divide both sides by -2)
x>-3


when you divide by a negative, you switch the direction of the inequality

divide -2x from both sides.
on the left it cancells the -2
x=-3
