Question
The values of x and y satisfying the equations 2x + 3y
= 77 and 3x + 2y = 73 are respectivelySolution
ATQ, Given Equations: 2x+3y=77 3x+2y=73 Multiply to Align Coefficients Multiply the first equation by 3 and the second by 2: 6x+9y=231 6x+4y=146 Subtract the Equations (6x+9y)−(6x+4y)=231−146 5y=85 y=17 Substitute y =17 in 2x+3y =77 2x+3(17) =77 2x+51=77 2x=26 x =13
