Question

express the following linear equation in the form ax+by+c=0 and indicate the values of a, b, c in -x+y=-7​

Answer 1

Answer:

Step-by-step explanation:

-x+y=7

y= 7 + x​

-x= 7-y so, ( multiplying <-1> on  both sides )

x= -7 +y

ax+by+c=0

a(-7 + y ) + b(7 + x​) + c = 0

-7a + ay + 7b + bx + c = 0
