Question

x + y = 6
2x - y = 3
The system of equations


a.has no solution
b.has one solution
c.is coincident

Answer 1

Add the equations together.

Answer 2

You get
3x = 9
x =3

Input your x value into the first equation.

3 + y = 6
y = 3

you will have one set of solutions.

Answer 3

what about this one?

5x + 2y = 5
3x - y = 14
Which of the following equations is not a result of solving the system of equations by addition?

a.11x = 19
b.11y = -55
c.11x = 33

Answer 4

5x + 2y = 5
3x - y = 14

5x + 2y = 5
6x -2y = 28

11x = 33

now if you wanted to solve for y.
15x + 6y = 15
-15x + 5y = -70
11y = -55

Option A, is incorrect.

Answer 5

okay and i got one last one

3x + 2y = 6
4x + y = 1
Solve the system of equations.

a.(-4/5, 21/5)
b.(8/11, -21/11)
c.no solution

Answer 6

y= -4x + 1

3x + 2(-4x+1) = 6
3x -8x + 2 = 6
-5x = 4
x = -4/5

option A

Answer 7
