Solve for x please
Show step by step and not just explain it ty

7x + 1 +4 + 18x = 180 ( co interior. angle)

7x+18x+1+4=180

25x+5=180

25x=180-5

x=175/25

x= 7

7x +1 = 7×7+1=504+18x=4+18×7=130

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
