Start by isolating one of the variables
x=-4y+2
Sub x into the other formula and solve for the y value of the solution.
3(-4y+2)+2y=11
-12y+6+2y=11
-12y+2y=11-6
-10y=5
y=-1/2
Sub the y value into the x formula you created.
x=-4(-1/2)+2
x=2+2
x=4
Therefore the solution is (4,-1/2) I think the answer is B unless the y value is actually -12.
Hope this helps :)
Using the given table, it is found that the mean number of children per household for these families is of 2.33.
<h3>What is the mean?</h3>
The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
Researching the problem on the internet, the table states that:
- 2 households have 4 children.
- 16 households have 2 children.
- 13 households have 3 children.
- 5 households have 1 children.
The total number of children is given by:
T = 2 x 4 + 16 x 2 + 13 x 3 + 5 x 1 = 84
Hence the mean number of children for the 36 households is given by:
M = 84/36 = 2.33.

Answer:
x = 4/3
Step-by-step explanation:
- you need to move -8x to the right side.
- 0=6x-8
- then, you need to move -8 to the left side.
- 8=6x
- you can get answer!
- x = 4/3
