Question

4x - 3y = 23, 3x + 4y = 11 solve by
elimination method​

Answer 1

Answer:

x =5, y =-1

Step-by-step explanation:

4x - 3y = 23 -> equation 1

3x + 4y = 11 -> equation 2

multiplying equation 1 by 4 and multiplying equation 2 by 3

we get

16x -12y = 92  -> equation 3

9x + 12y = 33 -> equation 4

Adding equation 3 and equation 4

25x = 125

x = 5

solving equation 2 with x =5

3*5 + 4y = 11

15 -11 = -4y

y = -1
