Answer:
X= 2.5 Y= 3.5
Step-by-step explanation:
2X+3Y =15.5
replace either x or y with your second equation
(2*(6-y))+3y=15.5
now you only have one variable
12-2y+3y=15.5
y=3.5
now insert your y value into the second equation provided
x+y=6
x+3.5=6
so x= 2.5
you can check your answer by inserting these numbers into the equations and it should work
Step-by-step explanation:
2x+3y=15.5 --- ①
x+y=6 --- ②
y=6-x --- ③
substitute ③ into ①
2x+3(6-x)=15.5
2x+18-3x=15.5
-x+18=15.5
18-15.5=x
x=2.5
y=6-x
y=6-2.5
y=3.5
hope this helps
