Question

solve equation 2x+3y=9 3x+4y=5 by using elimination method

Answer 1

2 x + 3 y = 9

3 x + 4 y = 5

Eliminate y

multiply (1)by -4

Multiply (2) by 3

-8 x -12 y = -36

9 x 12 y = 15

Add the two equations

1 x = -21

/ 1

x = -21

plug value of x in (1)

2 x + 3 y = 9

-42 + 3 y = 9

3 y = 9 + 42

3 y = 51

y = 17

Answer 2
