Question

PLEASEE IF YOU COULD ANSWER 5 QUESTIONS WILL BE HELPFULL

1.What is the solution to the system of equations?
4x+y=2
x-y=3

2.What is the solution to the system of equations?
x=4y+6
x-3y=4

3.Solve, using the substitution method.

3x + 2y = 11
x – 2 = – 4y

4.Solve, using the substitution method.

4x + 2y = 11
x – 2 = – 2y

5.Solve, using the substitution method.

y + 2x = 7
14 – 4x = 2y

A.
The solution is (1, 5)

B.
The solution is (21, 0)

C.
There are an infinite number of solutions.

D.
There is no solution.

Answer 1

Question 1 - x = 1 and y = -1

Question 2 - x = 4 and y = 20

Question 3 - x = 2/9 and y = -1/9

Question 4 - x = 2/9 and y = -2/9
