What is the first step needed to solve (1)x-3=-18?
Add 3 to both sides
Subtract 18 from both sides
Multiply both sides by 3
Divide both sides by 4

Option A, Add 3 to both sides

Step-by-step explanation:

Step 1:  Add 3 to both sides

x - 3 + 3 = -18 + 3

x = -15

 Option A, Add 3 to both sides

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

the answer to this question is 3/19
