## anonymous 3 years ago solve the following linear system x-2/3 + y+1/5 = 2 x+2/7 - y+5/7 = -2

1. anonymous

$\frac{ x-2 }{ 3 } + \frac{ y+1 }{ 5 } = 2$ $\frac{ x+2 }{ 7 } - \frac{ y+5 }{ 3 } = -2$

2. mathstudent55

Multiply the first equation by 15 and the second eqaution by 21 to get rid of denominators.

3. cwrw238

first get rid of the fractions by multiplying each equation by the LCM of the 2 denominators which is 15 and 21 as mathstudent55 stated

4. anonymous

then what

5. cwrw238

then solve for x and y by the elimination or substitution method

6. anonymous

what is the equation then?

8. cwrw238

ok i'll convert the first one for you |dw:1359322885676:dw|

9. cwrw238

now simplify it further: 5x - 10 + 3y + 3 = 30 5x + 3y = 30 + 10 - 3 5x + 3y = 37

10. cwrw238

now follow the same procedure with the second equation

k thanks

12. cwrw238

- you multiply through by 21 in this case

13. anonymous

yes i know thanks alot

you r welcome
