<span>A) 2x=96-14y
B) 9x=40-14y
Rearranging algebraically
</span>
A) 2x <span>+14y = 96
B) 9x </span><span>+14y
= 40</span>
Multiplying equation A by -1
A) -2x <span>-14y = -96 Then adding it to equation B
B) 9x </span><span>+14y
= 40
7x = -56
x = -8
</span><span>2*-8 = 96 -14y
-16 -96 = -14y
-112 = -14y
y = 8
</span>
The answer should be
24x3+44x-54x2-99

i did this before so ik im right
Answer:
ight so you put a dot at -2 and then go up like, go up -2 line until you look across and it says 7 and put a dot there
Step-by-step explanation:
Important:
The sum of the three angles inside
every triangle is always 180°.
First, look at the left triangle alone.
Two of its angles are 46° and 58° . (46° + 58° ) = 104°
That leaves (180° - 104° ) = 76° degrees for the third angle.
The third angle in that triangle is 'x'.
x = 76° .
At the point where 'x' and 'z' come together:
'x' and 'z' are a "linear pair".
Placed side-by-side, they form a straight line.
So (x + z) = 180° .
But x = 76°.
So z = (180° - 76°). z = 104° .
Now look at the the skinny triangle on the right alone.
The angle at the top is 13°, and z = 104°.
(13° + 104°) = 117° .
That leaves (180° - 117°) = 63° for the third angle.
'y' is the third angle.
y = 63° .
