Solution (6,0)

Work Step by Step

Given: 4x+9y=24 and y=$\frac{-1}{3}$x+2 Substitute value of y: 4x+9($\frac{-1}{3}$x+2)=24 Simplify: 4x+-3x+18=24 Simplify and subtract 18 from both sides : x=6 Substitute x value to find y: 4(6)+9y=24=> 24+9y=24 Subtract 24 from both sides we have 9y=0 => y=0 Solution (6,0)
