Question

Solve the following pair of equations:
* 2x - y - 6 = 0
* x - y - 2 = 0

• A. x = 2, y = - 2
• B. x = 1, y = - 1
• C. x = 4, y = 2
• D. x = 2, y = 1

Answer 1

The correct option is C x = 4, y = 2

Given:
2x - y - 6 = 0....... (i)
x - y - 2 = 0....... (ii)

$\left(i\right)-\left(ii\right)\Rightarrow x=4.......\left(iii\right)$
Substituting (iii) in (ii) gives y = 2.
Thus, x = 4, y = 2.
