Question 214762
The u.s. senate has 100 members, all democrats or repulbicans. Recently there were 12 more Democrats than Republicans. How many senators from each political party were there at that time? Choices for the number of republicans:38, 42, 44.
----------------------------
Quantity Equation: D + R = 100
Quantity Equation: D = R+12
-----------------------------------
Substitute to solve for "R":
R+12 + R = 100
2R = 88
R = 44 (# of Republicans)
