Question

substituting y= -13/2 solve y+7/3 = 1+3y-2/5​

Answer 1

Answer:

2x+y = 7

put,x =2

2(2)+y=7

4+y=7

y= -4+7

y=3

Answer 2

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

$y = \frac{ - 13}{2}$

$\frac{ - 13}{2} + \frac{7}{3} = \frac{1}{1} - \frac{26}{2} - \frac{2}{5}$

$\frac{ - 26 + 14}{6} = \frac{10 - 52 }{10}$

$\frac{ - 8}{6} = \frac{10 - 130 - 4}{10}$

$\frac{ - 8}{6} = \frac{ - 124}{6}$
