Answer: C
Step-by-step explanation:
Answer:
x=6 and y=2
Step-by-step explanation:
3x+5y=28
−4x−5y=−34
Add these equations to eliminate y:
−x=−6
Then solve −x=−6 for x:
−x=−6
(Divide both sides by -1)
x=6
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
3x+5y=28
Substitute 6 for x in 3x+5y=28:
(3)(6)+5y=28
5y+18=28 (Simplify both sides of the equation)
5y+18+−18=28+−18 (Add -18 to both sides)
5y=10
(Divide both sides by 5)
y=2
Answer:
= {-3.16227766, 3.16227766}
Step-by-step explanation:
If you multiply 48 (soccer teams in springtown) by 3, that will give you 144. then since 48 is 3 less than 3 times you add the 3 back to give you an answer of 147
