solving inequalities: 3x - 7 = 12(x = 1) - 2

[lnh]

3x-7=12(x=1)-2 I know you have to use the distributive property for 12(x+1) and then you'll have 3x-7=12x+12-2. Then you subtract 12-2 and your left with 3x-7=12x+10. After that im lost and we also have to find the solution set. HELP!!

Hi Inh:

Studying math will be easier if you get into the habit of double-checking what you write.

3x-7=12(x=1)-2 ? This is NOT an inequality ... also, two equal signs is a typographical error

We cannot help you until we know what the inequality sign is.

Use < or >.

You may use <= to mean "less than or equal to" and >= to mean "greater than or equal to".

Your work up to the point 3x - 7 = 12x + 10 is okay. Do you know that you're trying to get x all by itself on one side of the inequality sign? Continue by getting both terms that contain x together on one side and the constants together on the other side.

Then combine.

Depending upon the inequality symbol that you forgot to type, you'll end up with one of the following.

x > number

x < number

x >= number

x <= number
