Question

3x+4y=8 , 5x-6y=-9 what is the answer

Answer 1

Answer:

3x+4y=25 ...(1)

5x−6y=−9 ...(2)

Multiply (1) by 3 and (2) by 2

          9x+12y=75

(+) 10x−12y =−18

           19x=57

      x=3

Put  x = 3 in (2)

5x−6y=−9

 5(3)−6y=−9

6y=15+9

6y=24

y=4

Answer 2

Step-by-step explanation:

3x+4y=25 ...(1)

5x−6y=−9 ...(2)

Multiply (1) by 3 and (2) by 2

9x+12y=75

(+) 10x−12y =−18

19x=57

x=3

Put x = 3 in (2)

5x−6y=−9

5(3)−6y=−9

6y=15+9
