Question

Based on the census state A has 21 fewer electoral votes for president than state B. if the total number of electoral votes for these two states is 87 find the number for each state?

Answer 1

Let x = the number of electoral votes that B has

Let x- 21 = the number of electoral votes that A has

x + x - 21 = 87

2x = 108

x = 54

x - 21 = 54 - 21 = 33
