Question

solve the following pair of equations by elimination method ×+2y =11/2×-y =2​

Answer 1

Step-by-step explanation:

$x + 2y = \frac{11}{2} \\ x \: - y = 2 \\ - \: \: + \: \: \: \: \: \: - \\ 3y = \frac{7}{2} \\ y = \frac{7}{6} \\ substitute \: y \: in \: \\ x - \frac{7}{2} = 2 \\ x = \frac{11}{2}$
