Question

solve each system. Then drag each one to the column headed by a point which could be its solution.

2x-6y=10
x+8y=5

3x-y=-5
x+4y=7

2x-2y=12
-2x-3y=-22

x-y=2
2x+y=13

(5,y) (x,2)

Part 1) The solution of the system of equations is the point (5,0) -> the solution could be (5,y)

Part 2) The solution of the system of equations is the point (-1,2) –> the solution could be (x,2)

Part 3) The solution of the system of equations is the point (8,2) -> the solution could be (x,2)

Part 4) The solution of the system of equations is the point (5,3) -> the solution could be (5,y)

Step-by-step explanation:

Part 1) we have

—-> equation A

—> equation B

Solve the system by elimination

Multiply equation B by -2 both sides

—-> equation C

Adds equation A and equation C

Find the value of x

substitute the value of y in any equation

therefore

The solution of the system of equations is the point (5,0) -> the solution could be (5,y)

Part 2) we have

—-> —-> equation A

—> equation B

Solve the system by substitution

substitute equation A in equation B

solve for x

Find the value of y

therefore

The solution of the system of equations is the point (-1,2) –> the solution could be (x,2)

Part 3) we have

—-> equation A

—> equation B

Solve the system by elimination

Adds equation A and equation B

Find the value of x

substitute the value of y in any equation

therefore

The solution of the system of equations is the point (8,2) -> the solution could be (x,2)

Part 4) we have

—-> —-> equation A

—> equation B

Solve the system by substitution

substitute equation A in equation B

solve for x

Find the value of y

therefore

The solution of the system of equations is the point (5,3) -> the solution could be (5,y)
