Ok let's do this*pops knuckles*
let's add the first side

order of operations demands that we do multiplication first(P.E.M.D.A.S)
so

now we can add the 1 from

into our six

now we substract

now we have

now we focus on the
other side

since 5 is in paranthesis we use something called the distributive property. it mean we will multiply the 5 by both of the 2.

now we have

(the three is from the original equation)
now we plug in our final numbers

or

I hope this helps
Answer:
x = 61, y = 29
Step-by-step explanation:
29+x = 90
x = 61
x + y = 90
y + 61 = 90
y = 29

Discussion.
Not directly. But the quadratic formula can do it. But that's not your question.
the factors you get must contain the factors for 1 which are 1 and - 1
These factors must add to - 5. There's no way that will happen with 1 and - 1 and you would be creative math if you tried to say that you could make one of the factors (x -1-1-1-1-1-1). That creates a whole new question.
Given the equation :

We will use estimation to find the value of the given expression
So, the best estimation for the number 576 is = 600
The best estimation for the number 8 is = 10
So, the given expression is approximately = 600 ÷ 10 = 60
===================================================================
We can calculate the error of the approximation as following :
The actual value is : 576 ÷ 8 = 72
So, the difference is = 72 - 60 = 12
so, the percentage of error will be :

The first thing you should do in this case is to compose both functions:
f (x) = x + 7
g (x) = 1 / (x-13)
Making the composition
f (g (x)) = (1 / (x-13)) + 7
f (g (x)) = (7 (x-13) +1) / (x-13)
Answer:
The domain of the function is:
x other than 13
