No, you did it incorrectly. The answer is y=-3
How I did this was;
2y+x=-15 x=3y
2y+3y=-15
If you multiply a whole number by a negative number you get a negative number, so I found a, number that could be multiplied into two different numbers that cloud be added together to have a sum of -15.
I really hope that made sense.

3 pieces of wood have a total length of 32 m. The second piece is twice the size of the first and the third piece is 2 more mete
andreev551 [17]

Answer:

X + Y + Z = 32

X2 = Y

X3 + 2 = Z

X + X2 + X3 + 2 = 32

Make X alone

There is a 2 so we subtract 2 from both sides

X + X2 + X3 = 30

Add the X's up

X + X2 + X3 = X6

X6 = 30

Divide by 6

30 / 6 = 5

You are left with X=5

The first piece of wood has a length of 5

5 x 2 = 10

The second piece has a value of 10

5 x 3 + 2 = 17

The third piece is 17

Hope this helps. If you have any questions you may ask.
