5x+45=1605
-45 from both sides
5x=1560
divide each side by 5
x=312
Adding 19w to both sides.
Hope this helps!

3x +7x = 7x +7x -30
10x = 30
10x/10 = 30/10
x = 3

Answer:
Number of en at the lecture = 18
Step-by-step explanation:
Let the men at lecture be 2x
And women at lecture be 5x.
Remember ratio of men and women is 2 to 5.
Total number of people at the lecture = 63
i.e 2x + 5x = 63
or 7x = 63
or x = 63 /7
or x =9
Hence , Men at the lecture = 2x = 2*9 = 18
And women at the lecture = 5x = 5*9 = 45
