Which of the following statements could be a correct step in solving this equation: 12x−7=13(x−12)

A. 12x−7=13x−12

B. 3x−42=2(x−12)

C. 3x−7=2(x−12)

D. 3x−7=2x−12

A

Step-by-step explanation:

I think the answer is A because you have to use 13 to multiply what's in the bracket in order to collect like terms but 13 *12 won't give you 12. That's the reason why am confused

angles 1 and 3 are vertical angles, meaning that they are equal to each other. to solve this you may set angle 1 and 3 equal to each other and just solve for x like

110 = 2x + 10

100 = 2x

50 = x

check:

110 = 2* 50 + 10

110 = 100 + 10

110 = 110

hope this !
