5(-3p + 7) + 5(p - 1) = 0
-15p + 35 + 5p - 5 = 0
-10p + 30 = 0
-10p = -30
p = 3

Well first u gotta simplify the equation by multiplying the outside number (the 5) into the parenthesis.

Original: 5(-3p+7)
simplified: -15p+35

and then you do the same for the other part.

Original: 5(p-1)
Simplified: 5p-5

Now thats done, you now have the new equation as -15+35+5p-5

And finally you combine like terms and your final answer should be -10p+30

Given the Function:

sergey [27]

F(x)=-2e^x
x=3
f(3)=-2e^3
pemdas so exponents first
e^3
e=2.718281828454590
cube that
20.0855

now we have
-2 times 20.0855=-40.1711

answer should be -40.1711
(I see what you did wrong, if -6=-2 times e^3, divide -2, 3=e^3, maybe you just put -2 times 3 by mistake)
