Answer: y is 23 and x is 139 so x + y = 162
Step-by-step explanation:
(23-x)+(2x+18)=180
41+x=180
x=180-41
x=139
It means that all values of x would make it true. Also take a look at the equation when we simplify:
4x + 7 = 1 + 4x + 6
Which simplified turns into
4x + 7 = 4x + 7
So no matter what value you put for x, it will be the same on both sides, making all values true for x.
F(x) = -4sin(2x + π) - 5

I don't really understand the question
The answer is 3x-3. You have to distribute the 3 to both of the variables in the equations. The 1 in the parentheses is a negative and multiplying the 3 will result in a negative 3.
