What value of x makes the equation below true?

4x - (3x - 5) = 2x + 11
select one:
a. x = -4
b. all real numbers
c. x = -6
d. x = 2

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.

Ahypothesis is: a the average squared deviations about the mean of a distribution of values b) an empirically testable statement that is an unproven supposition developed in order to explain phenomena a statement that asserts the status quo; that is, any change from what has been c) thought to be true is due to random sampling order da statement that is the opposite of the null hypothesis e) the error made by rejecting the null hypothesis when it is true

1.based of the diagrams what is the the value of x? 2.how would you verify your answer for x
