Question

Q17. On solving the following pair of linear equations:2x – y = 2; 5x + 2y = 14, values of x and y are ................ and ................... respectively.

Answer 1

Answer:

2, 2

Step-by-step explanation:

2x - y = 2 ----- eq 1

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

Multiplying eq 1 with number 2.

4x - 2y = 4 ----- eq 3

Adding eq 2 and eq 3

9x = 18

x = 2

2x - y = 2

4 - y = 2

y = 2
