For a recent year, the number of men in the senate totaled 3 more than 3 times the number of women. Find the number of men and the number of women in the senate given that the senate has 111 members
+122 Let x be the number of women in the senate and y the number of men in the senate.'
We know that y=3x+3 (3 + 3 times the number of women)
We know that x+y=111.
With that you can now substitute y for 3x+3 and get the following:
x+y=111 => x+3x+3=111
4x+3=111
4x=111-3
4x=108
x=108/4
x=27
y=3*27+3
y=84
Check by 84+27=111
Hope it helps
cheers
