bonufazy [111]
To start you would turn 4 2/3 into a mixed number by multiplying 4 and 3 and adding 2. Your mixed number would be 14/3. Then, you want to find how many 2/3 yard long pieces of string will fit into 14/3 so you devid 14/3 by 2/3 and you get 7. So 7 2/3 yard pieces of string will fit into 4 2/3.

To check your work you can multiply 2/3 by 7 and you will get 4 2/3.

X + 5y +3z = 4<br> 4y – z=3<br> 6x – 2y + 4z = 0
Leno4ka [110]

Answer:

x = \frac{1}{4}

y = \frac{3}{4}

z = 0

Step-by-step explanation:

You first need to solve for a variable, it won't be as easy as x = 3, you are looking to replace a variable with another equation.

For example, the second equation, 4y-z=3, I can either solve for y or z. It won't be a numerical value but it will get you a step closer.

4y-z=3

4y=z+3

y = \frac{z}{4} +\frac{3}{4}

Then you are able to use substitution to negate one of the variables and solve for the other two variables. I won't type that but I think you get the idea.
