Question

how to solve 5x+3y=15

Answer 1

Its a graph question
solution: 5x+3y=15
WE NEED TO SOLVE FOR Y ALWAYS BCS Y IS DEPENDENT ON X!!!
3y = 15-5x
y= (15-5x) / 3

Answer 2

the value cannot be found, but:

5x+3y=15
means:
3y=15-5x
3y/3=(15-5x)/3
$y=\frac{15-5x}{3}$

5x+3y=15
means
5x=15-3x
5x/5=(15-36)/5
$x=\frac{15-3x}5$

We generally take y.

Ans=$y=\frac{15-5x}{3}$
