One number is 1 more than 4 times another. their product is 18. find the numbers.

Ihope this out  number 1=xnumber 2=y  x=5+2yx*y=18  substitute 5+2y into the second equation.  (5+2y)*y=185y+2y^2=182y^2+5y-18=0(2y+9)(y-2)=02y=-9, y-2=0y=-9/2 and y=2  to find x, plug -9/2 and 2 in for y into x=5+2y.  it makes more sense to use 2 instead of -9/2. so here we go.  x=5+2(2)x=5+4x=9  to double check our work, solve the second equation with our x and y values.  x*y=189*2=18  therefore,  x=9  and  y=2.
