B.) 8

C.) 9

D.) 22

E.) 44

x + y = 26

x - y = 18

---------------

2x = 44 {added the two equations together, eliminating the y}

x = 22 {divided each side by 2}

x + y = 26 {top original equation}

22 + y = 26 {substituted 22, in for x, into top original equation}

y = 4 {subtracted 22 from each side}

**A.) 4**
