Question

solve carlos scored 15 more points that john.if the product of the two points toal 154 how many points did each boy score

Answer 1

x=15+y
x*y=154

(15+y)*y=154

then just solve for y and plug that into the first eqn and solve for x

Answer 2

Let x=john points
x+15 = carlos points
x(x+15) = 154 given
x^2 + 15x =154 or x^2 + 15x -154=0
(x+22)(x-7)=0
x=7
x+15 = 22
carlos 22 points
John 7 points
