### Need help on intermediate algebraic equation(s)

Thank you so much for visiting this thread. I recently started my freshman year of college with Math 1010 (intermediate algebra). So far it has been fairly easy and just a review of things, but the final two questions on one of my tests had me completely stumped, and left me in need of an explanation and answer (detailed if your time permits);

First Question:
2(t - 2) - 3(3t - 1) = 8 - 5(5t + 4)

Second Question:
-2(a - 2) - [3 - 2 (4a - 1)]

I am not that great at using the Distributive Property on equations with more than 3 terms. I can perform (below) easily.
2 (t - 4)
2(t) + 2(-4)

But not (below)
2(9 - 5 [-4x - 3])

Hi;

Welcome to the forum. I am assuming you want to solve for t?

Expand it out.

Divide both sides by -18.

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Thank you very much. In your first step, of expanding it out, could you give me your step-by-step equations, with the distributive property as well? I would really appreciate it, as I have always had issues with the distributive property.

Hi;

I did not use the distributive property. I used multiplication and simplification.

The second question is not an equation, there is no equal sign. What do you want to do with it.?

It can be simplified to look like this,

6a - 1

You did use the distributive property in expanding the brackets.

The limit operator is just an excuse for doing something you know you can't.

Not really.
