Question

express 3x+5y=7.5 in the form of ax+by+c=0 and indicate the value of a,​

Answer 1

ax + by + c = 0

; 3x + 5y -7.5 = 0

Value of A = 3

Answer 2

Answer:

a= 3

b= 5 and

c= -7.5

The following expression is 3x+5y= 7.5 ( Transposing 7.5 in LHS so it becomes in minus so,

3x+5y=7.5

3x+5y-7.5 = 0

so, here ax+by+c

=3x+5y-7.5 so,

a=3

b=5 and

c=7.5
