Question

Which of the following is the valid classification of the system given below?

$ 7x + 2y = 24
| 2x + 1 = y

Answer 1

Explanation:

The system of equation given is a simultaneous equation

7x + 2y = 24 ...... 1

2x + 1 = y ......... 2

Rearrange

7x + 2y = 24 .... *1

| 2x - y = -1 ..... * 2

Use elimination method

7x + 2y = 24

4x - 2y = -2

add

7x+4x = 24-2

11x = 22

x = 22/11

x = 2

Substitute x = 2 into 2

2x+1 = y

y 2(2)+1

y = 4+1

y = 5

Hence x = 2, y = 5

The system of equation is a simultaneous equation
