Question

2x−9y=14 x=−6y+7 ​ x= y=

Answer 1

x =7, y = 0

Explanation:

`2x - 9y = 14...(1) \\ \\ x = - 6y + 7...(2) \\ \\ from \: equation \: (1) \: and \: (2) \\ \\ 2( - 6y + 7) - 9y = 14 \\ \\ - 12y + 14 - 9y = 14 \\ \\ - 21y = 14 - 14 \\ \\ - 21y = 0 \\ \\ y = (0)/( - 21) \\ \\ \huge \red{ y = 0} \\ \\ x = - 6 * 0 + 7 \\ \\ x = 0 + 7 \\ \\ \huge \purple{x = 7}`
