Answer:
30xy
Step-by-step explanation:
I divided this shape into a square and a rectangle.
Solve:
First I multiplied 2x and 3y
2x*3y= 6xy
Then I multiplied 6x and 4y
6x*4y= 24xy
Then I added them together
24xy+6xy= 30xy
Hope this helps!
Subtract 2(first equation) from the second, and 3(first equation) from the third to eliminate <em>x</em> :
(2<em>x</em> + 3<em>y</em> + <em>z</em>) - 2(<em>x</em> + <em>y</em> + <em>z</em>) = 16 - 2*9
<em>y</em> - <em>z</em> = -2
(3<em>x</em> - 4<em>y</em> + 2<em>z</em>) - 3(<em>x</em> + <em>y</em> + <em>z</em>) = 1 - 3*9
-7<em>y</em> - <em>z</em> = -26
Now subtract either equation with <em>y</em> and <em>z</em> from the other to eliminate <em>z</em>. If we take the first from the second, we get
(-7<em>y</em> - <em>z</em>) - (<em>y</em> - <em>z</em>) = -26 - (-2)
-8<em>y</em> = -24
<em>y</em> = 3
Then
<em>y</em> - <em>z</em> = 3 - <em>z</em> = -2
<em>z</em> = 5
And lastly,
<em>x</em> + <em>y</em> + <em>z</em> = <em>x</em> + 3 + 5 = 9
<em>x</em> = 1
I added 8 on both sides to get 12=3x then I divided by 3 on both sides to get x=4
