Question

express the following linear equations in the form ax+by+c=0 and indicate the value of a,b and c in each case
1.-2x+3y=12
2.x-y/2-5=0
3.2x+3y=9.35
4.3x=-7y
5. 2x+5=0
6. y-5=0
7.4=3x
8.y=x/2​

Answer 1

Answer:

1. -2x+3y=12

=ax+by+c

=-2x+3y-12=0

a=-2

b=3

c=-12

2. x-y/2-5=0

=1x-y/2-5=0

a=1

b=-1/2

c=-5

3. 2x+3y=9.35

=2x+3y-9.35=0

a =2

b=3

c=-9.35

4. 3x=-7y

=3x+7y+0=0

a=3

b=7

c=0

5. 2x+5=0

=2x+0y+5=0

a=2

b=0

c=5

6. y-5=0

=0x+1y-5=0

a=0

b=1

c=-5

7. 4=3x

= -3x+0y+4=0

a=-3

b=0

c=4

8. y=x/2

= -x/2+y+0=0

a=-1/2

b=1

c=0
