## anonymous 5 years ago Solve, x-(3/5) = (7/10 x minus 3 over 5 equals 7 over 10

Multiply both sides by 10, you get: $10x-6=7 \implies 10x=13 \implies x={13 \over 10}$

@AnwarA Where did you get the 6 from?

3. anonymous

$-\frac{3}{5}\times 10=-6$

4. anonymous

As satellite said.

5. anonymous

The answer in the book says its negative 1 over 10.

6. anonymous

I wanna know the steps to solve this equation...

7. anonymous

is it $x-\frac{3}{5}=\frac{7}{10}$

8. anonymous

or $\frac{x-3}{5}=\frac{7}{10}$?

9. anonymous

yes, the first one

10. anonymous

well then the answer in the book is wrong, because anwar is right.

11. anonymous

one step problem if you do not mind the fractions: $x-\frac{3}{5}=\frac{7}{10}$ add $\frac{3}{5}$ to both sides to get $x=\frac{7}{10}+\frac{3}{5}=\frac{7}{10}+\frac{6}{10}=\frac{13}{10}$

12. anonymous

No i figured it out. 3/5 is equal to 6/10 so to solve for x i have to get x alone so i minus 6/10 from both sides & 7/10 minus 6/10 equals 1/10 so that makes x=1/10

13. gw2011

3/5 does equal 6/10 but you have to add 6/10 to both sides and not subtract it because you have a -3/5 and not a +3/5

14. anonymous

unfortunately $-\frac{3}{5}-\frac{3}{5}=-\frac{6}{5}$ not 0. you have to add $\frac{3}{5}$ to both sides

15. anonymous

scratch that, idk why it says 1/10 for the answer in the book. i'll leave that for the teacher to explain.thanks anyways :)
