The two equations given in the question are y = - x + 5 and 5x + 2y =14 Now we will have to put the value of y from the first equation in the second equation and then calculate. 5x + 2y = 14 5x + 2(-x + 5) = 14 5x - 2x + 10 = 14 3x = 14 - 10 3x = 4 x = 4/3 Now we have to put the value of x in the first equation for determining the value of y y = - x + 5 = - (4/3) + 5 = (15 - 4)/3 = 11/3 So the value of x is 4/3 and the value of y is 11/3.
