Answer:
p = -13
Step-by-step explanation:
Simultaneous Equations
3x + y = 4
5x - y = 22
The signs of the matching values aren't the same so we add the rest of the equations.
8x = 26
Divide both sides by 8 to get x = 3.25
Now substitute back into the first equation.
(3 x 3.25) + y = 4
9.75 + y = 4
Subtract 9.75 from both sides
y = -5.75
That should be the answer 116,144.
The answer is A.27 it is 9 * 3 is how you get it
I think the 3 is an exponent so we can write the expression as
18 * 4y^3
= 72y^3
