Step-by-step explanation:
If you are solving for x then this is how:
So you have
23x +15y=2
first subtract 15 from both sides
23x = 2-15y
then divide by 23 on both sides
x= (2-15y)/23
If you are solving for y:
23x +15y=2
subtract 23x from both sides
15y=2-23x
then divide by 15 on both sides
y= (2-23x)/15
