Question 846916: 5+y/-8=11 how do i do this?
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! 5 + y / -8 = 11
you would first subtract 5 from both sides of the equation to get:
5 + y / -8 - 5 = 11 - 5
you would then simplify that to get:
y / -8 = 6
you would then multiply both sides of the equation by 8 to get:
y / -8 * -8 = 6 * -8
you would then simplify that to get:
y = -48
that's your solution.
you confirm this solution by replacing y in the original equation with -8 and evaluating that equation to make sure the equation holds true.
when you do that, 5 + y/-8 = 11 becomes 5 + -48/-8 = 11
since -48 / -8 is equal to +6, your equation becomes:
5 + 6 = 11
combine like terms to get:
11 = 11 which is true, confirming that the value of y = -48 is the solution to the original equation.
if you do not know how to solve equations and how to apply the basic principles of solving equations, then you should study up on that.
