Answer:
x=90/16,y=-150/16
Step-by-step explanation:
Simultaneous equation and we are to use elimination method
9x+y=30...(1)
6x-y=15..(2)
Add (1) and (2)
16x=15
Divide both sides by 16
x=15/16
Then substitute the value of x into (2)
6(15/16)-y=15
90/16-y=15
Substrate 15 from both sides
90/16-y-15=0
Add y to both sides
90/16-15=y
Lcm for only the left side which is 16
90-240/16=y
-150/16=y
Therefore x is 90/16 and y is -150/16
