2x-3y=123x+4y =22elemination method​

Answer»

Step-by-step explanation:

2x-3y=12----1

6x-9y=36----(MULTIPLYING THROUGHOUT by 3)----- 2

3x+4y=22-----3

6x+8y=44----(multiplying throughout by 2)----4

subtracting equ4 from equ2

6x-9y=36

- 6x+8y=44

-----------------

-y = -8

y=8

substituting y=8 in equ 1

2x - 3×8 = 12

2x - 24= 12

2x = 12 + 24

2x = 36

x = 36 ÷ 2

x = 18

(18,8) is the solution for the given simultaneous EQUATIONS.
