Complete the following activity to solve simultaneous equations :
`4x+ 3y = 18 " "...(1) 5x - 3y = 9 " " ` ...(2)
Adding equations (1) and (2) , `+{:(4x+3y=18" ...(1)"),(5x-3y=9" ...(2)"),(bar(squarex" "=square)):}`
` :. X = (square)/(square ) " " :. X = square`
Substituting x = 3 in equation (1) ,
` 4 xx square + 3y = 18 " " :. 3y = 18 - square " " :. 3y = square `
` :. y = 2 `
(x,y ) = `(square, square ) ` is the solution
