Solve for X.

-18=9-3x

x=9

Step-by-step explanation:

To solve for x, we need to get it by itself. To do this, we need to do the opposite of what is being done to the equation, and anything we do on one side must be done on the other.

-18=9-3x

Subtract 9 from both sides

-18-9=9-9 -3x

-27=-3x

Divide both sides by -3

-27/-3= -3x/-3

9=x

the answer is somewhere there guys it really . there im just not gonna answer

step-by-step explanation:

but i'm guessing ur first option tho

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
