i need help..

anonymous · Answer

$$\frac{ 7 }{ 10 }m-17=-\frac{ 1 }{ 2 }m-5 $$         
solve..

anonymous · Answer

OK, hold on here a second.... I had it almost done, and pushed the wrong button on this thing....

anonymous · Answer

1) Add 17 to each side.

anonymous · Answer

2) add (1/2)m to each side

anonymous · Answer

Herd the terms with m in them to one side, the ones without to the other, then simplify and divide.  Like this$$\frac{7}{10}m−17=−\frac{1}{2}m−5 $$$$\frac{7}{10}m+\frac{1}{2}m=−5 +17$$$$\frac{6}{5}m=12 \implies m=10$$

anonymous · Answer

This is always the first couple steps for algebra problems. You want to get constants on one side and variables on the other.

anonymous · Answer

The big deal on solving this kind of equation is to get the variable terms together, so you can simplify and solve.

anonymous · Answer

I agree with all of animal's steps except I would have kept the fraction as 12/10. That way  when you times each side by the reciprocals the 12's just cancel

anonymous · Answer

Apparently, ChmE and I seem to be on the same page here...

anonymous · Answer

ok thank you guys very much

cwrw238 · Answer

another way to do this would be to multiply through by 10 on the first step

cwrw238 · Answer

thus getting rid of the fractions immediately

anonymous · Answer

ok i will try that next time @cwrw238

cwrw238 · Answer

ok
