First you would want to multiply 5 and 7 once you get your answer subtract it from 99
Answer:
11
Step-by-step explanation:
your welcome bro.
The first step to solving this is to write the number in exponential form
2

=

since the bases are the same,, set the exponents equal to one another
-IxI = 7
now change the signs on both sides of the equations
IxI = -7
this equation is false for any value of x because the absolute value function needs to always be positive or 0,, which is not the case for this expression
x ∈ ∅
this means that the answer to your question is x ∈ ∅
let me know if you have any further questions
:)
Im pretty sure its -y^2+3y+13x-3
