Need simple(?) algebra help please!
I'm not sure how to solve for these types of algebra equations. Could you please tell me the steps required?
1. 170(x) - 70 (1-x) = 0. Solve for x. X should be 0.292 but I am having trouble finding out how.
The next equation:
2. -6(0.5) - 20(x) + 14(1-0.5-x) = 0
Thanks so much!
Re: Need simple(?) algebra help please!
When solving these types of equations it's best to gather up all the x's in one place. So,
Step 1. Multiply out any brackets:
becomes which then becomes
the last equation is because , i.e., a minus multiplied by a minus gives a plus.
So after step 1 we have .
Step 2. Put all the x's together. 170x + 70x becomes 240x because I can add the x's (I can add the terms that are alike).
So now the equation becomes,
Step 3. Get all the x terms on one side and all the normal numbers on the other. We can add 70 to both sides of the equation to get rid of the -70.
So the equation becomes,
Step 4. Now we want to get the x on its own. We divide both sides by 240,
becomes just and becomes 0.29166666...
So we have,
