If \(2 \left[ {\begin{array}{*{20}{c}} x&5\\ 7&{y - 3} \end{array}} \right] + \left[ {\begin{array}{*{20}{c}} 3&4\\ 1&2 \end{array}} \right] = \left[ {\begin{array}{*{20}{c}} 7&{14}\\ {15}&{14} \end{array}} \right]\) then find the value of x and y ?
1
x = 9 and y = 2
2
x = 2 and y = 9
3
x = 3 and y = 15
4
x = 15 and y = 3
