Question

find the2 solution of -3x+4y=12​

Answer 1

Answer:

(-4,0) and (8/3,1)

Step-by-step explanation:

let y be 0

-3x + 4(0)= 12

-3x = 12

x=12/-3

x = -4. (-4,0)

let y be 1

-3x + 4(1)= 12

-3x+ 4 = 12

-3x= 12 - 4

x = 8/3. (8/3,1)

Answer 2

Step-by-step explanation:

-3x+4y=12

x+4y=12+3

x+4y=15

x+y=15-4

x+y=11

x=11-y

y=11-x
