Question

5y = 3478 - 3c if the equation above, c is a constant. If y = 8 is a solution to the equation, what is the value of c?

1 Answer

  • What you would do is simply plug in 8 where y is and solve.
    5(8)=3478-3c -Times 5 by 8
    40=3478-3c  -Add 3c to the opposite side of the equal sign
    40+3c=3478  -Subtract 40 from the opposite side of the equal sign
    3c=3438  -Divide equation by 3
     c=1146

    Hope this helps! :)
