Question

3x-4y=12
find three soulutions to this problem​

Answer 1

Answer:

Given equation is 3x+4y=12

If x=1 put in equation we get

(i)3×1+4y=12

⇒3+4y=12

⇒4y=12−3

⇒4y=9

⇒y=5

If x=2 put in equation we get

(ii)3×2+4y=12

⇒6+4y=12

⇒4y=12−6

⇒4y=6

⇒y= 2

If x=3 put in equation we get

(iii)3×3+4y=12

⇒9+4y=12

⇒4y=12-9

⇒4y=3

⇒y= -1

Step-by-step explanation:

Hope it will be help you

Answer 2

3x-4y-12=0

4y-12=-3x

4(y-3)=3x

4(y-3)/3=x(assume x to be 4(y-3)/3

3x-4y=12

3*4(y-3)/3=12

4*(y-3)=12

y-3=3

y=3+3

y= 6

for x

3x-4*6=12

3x-24=12

3x=12+24

x=36/3

x=12
