3. Solve the equation using substitution. x + y = 8 y = 3x

Replace y = 3x in
x+y=8
x + 3x = 8

carry on

I CANT WRITE HELLPP AFFKKGSJ @ANSWERS

Answers is right! TY so much!!

you guys are angels, id fail without you

yes i agree

Still right lol

Still correct :)

they are still correct

Just in case someone wanted to make sure they had the same questions!

1) solve the system using substitution
X + y = 8
y = 3x

A) (2,6)

2) Solve the system using substitution
2x + 2y = 38
Y= x + 3

A) (8,11)

3) solve the system using substitution
Y = 8 - x
7 = 2 - y

A) (13,-5)

4) solve the system using substitution
3x + 2y = 23
1/2x - 4 = y

A) (31/4, -1/8)

5) solve the system using substitution
Y - 2x = 3
3x - 2y = 5

A) (-11, -19)

6) solve the system using substitution
4x = 3y - 2
18 = 3x + y

A) (4,6)

7) adult tickets to a play cost $22. Tickets for children cost $15. Tickets for a group of 1a people cost a total of $228. Write and solve a system of equations to ind how many children and how many adults were in the group

A) 2 children, 9 adults

8) tell whether the system has one solution, infinitely many solutions, or no solution.
6y = -5x + 24
2.5x + 3y = 12

A) infinitely many solutions

9) tell whether the system has one solution, infinitely many solutions, or no solution.
X = -7y + 34
X + 7y = 32

A) no solution

10) tell whether the system has one solution, infinitely many solutions, or no solution.
1.5x + 2y = 11
3x + 6y = 22

A) one solution

Sorry if there are any mistakes, im on mobile

Solve this :

y = 1/2x − 5 + x + 3y = 20

still correct
