Answer:
32
Step-by-step explanation:
If <em>y</em> is 2 times as much as <em>x</em>, then 1 = 2
5 x 3 = 15 + 1 = 16
10 x 3 = 30 + 2 = 32, or 16 x 2 = 32
Please tell me if I'm wrong.
11+2x = 8*(x-5)
11+2x = 8x-40
11+40+2x = 8x-40+40
51+2x-2x=8x-2x
51 = 6x
51/6 = 6x/6
8.5 = x
Therefore, your number is 8.5.
