Y=2x-5 3x+8y+32=56 What does y and x equal?

AVprozaik [17]3 years ago
5 0
Y = 2x - 5
3x + 8y + 32 = 56
3x + 8(2x - 5) + 32 = 56
3x + 8(2x) - 8(5) + 32 = 56
3x + 16x - 40 + 32 = 56
19x - 8 = 56
<u>      + 8   + 8</u>
     <u>19x</u> = <u>64</u>
      19     19
         x = 3.4
y = 2(3.4) - 5
y = 6.8 - 5
y = 1.8
(x, y) = (3.4, 1.8)

Gemiola [76]

Answer:

There would have been three people in the group.

Step-by-step explanation:

This is because if you add 2/3 together until you get that amount, it will add up to having three people. If this sounds confusing, here is a visual thing to help.

2/3+2/3=4/3 which can also equal 1 1/3

1 1/3 + 2/3 =2

you added 2/3 together three times to get two, so three is the answer.

Hope this helps!
