Answer:

28

Step-by-step explanation:

Givens

Game 1: 30

Game 2: 18

Game 3: 28

Game 4: x

Solution

(30 + 18 + 28 + x) / 4 = 26                 Multiply both sides by 4

4* (30 + 18 + 28 + x) / 4 = 26 * 4       The 4s on the left cancel

30 + 18 + 28 + x = 104                       Add the 3 other numbers together

76 + x = 104                                       Subtract 76 from both sides.

76-76+x = 104-76                              The 76s on the left disappear.

x = 28

Answer

in the next game he must score 28 points to average 26
