Answer

178 Republicans, 256 Democrats

Work Step by Step

If we represent the number of Republicans with x, then the number of Democrats is represented by x + 78 because there are 78 more Democrats than Republicans. Since the total number is 434, the equation is: x + (x + 78) = 434 Solve for x; 2x + 78 = 434 2x = 356 x = 178 There are x= 178 Republicans, and x + 78 = 178 + 78 = 256 Democrats.
