Solve for x.<br> 8(5 + x) = 11(9 + x)<br> Answer as a fraction.
7nadin3 [17]

distribute the 8 to the 5 and x. then distribute 11 to 9 and x.

(40+8x)=(99+11x)

-11x -11x

-3x+40=99

-40 -40

-3x= 59

divide three on both sides

x=59/-3

I'm using double number lines. Martin bought 3 DVDs for $15.00 on Black Friday. At this price, how much would 8 DVDs cost?
bagirrra123 [75]
First of all, I find it easiest to write n equation.

3 / 15 x 8 = 

Now that we have an equation, we can figure out a solution. 

3 / 15 = 5
5 x 8 = 40

So 8 DVD's would cost $40.00.
