Answers
x=13/5. and y =16/5
Step-by-step explanation:
By elimination method:
multipy 3 in the first equation
then the first equation becomes
3x+6y=27
the second equation remains as it is..
substract first and second equation
3x+6y=27
3x + y = 11
5y=16therefore y=16/5
substituting the value of y in equation two i.e the second equation:
3x+16/5=11
3x=11-16/5
3x=55-16/5
3x=39/5
x=39/15
x=13/5
Answer: x=13/5 & y=16/5
Step-by-step explanation: x+y=11
x+2y+(-2y)=9+(-2y)
x=-2y+9
3x+y=11
3(-2y+9)+y=11
-5y+27=11
-5y+27+(-27)=11+(-27)
-5=16
-5/-5=-16/-5
y=16/5
x=-2y+9
x=-2(16/5)+9
x=13/5
