Answer:
the answer is 9/8 or 1 and 1/8
Step-by-step explanation:
divide 3/4 by 2 to get 3/8 and then multiply 3/8 by 3 (since its tripling) to get 9/8 which can also be written as 1 1/8. Hope this helps!
is that what you looking for
x=1 y=7
−5x+2y=9
y=7x
Substitute the second equation into the first
-5x +2(7x) = 9
Distribute
-5x +14x = 9
Combine like terms
9x=9
Divide by 9
9x/9 =9/9
x= 1
Now find y
y = 7(1)
y = 7
