The junior high band sold candy for the fundraiser. the profit from the candy sale was $180. the girls sold three times as much candy as the boys. how much of the total profit did the boys provide?

Let X the price of candy the girls sold
and Y for the boys
so we have X + Y = 180
                   and X = 3Y
so X + Y = 180
     X - 3Y =0
is a system of equation for solving
it is 4Y=180 implies Y= 45, and X =3Y =3 .45 =135

so the boys did provide $45

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this
