Answer:
Value of x is 34
Step-by-step explanation:
The figure is a quadrilateral;
Angles given are; 2x°, 88°,108° and (3x - 6)°
We already know that the interior angles of a quadrilateral add up to 360°
Therefore, to get the value of x;
2x° + 88° + 108° + (3x - 6)° = 360
5x° + 190° = 360°
5x° = 170°
x = 34°
Thus, the value of x is 34

Adults = 9
Children = 2
Let x be the number of adults.
11-x is the number of children.
22x + 15(11-x) = 228
22x + 165 - 15x = 228
22x - 15x = 228 - 165
7x = 63
7x / 7 = 63 / 7
x = 9 number of adults.
11 - x = 11 - 9 = 2 number of children.
To check:
22x + 15(11-x) = 228
22(9) + 15(11-9) = 228
198 + 30 = 228
228 = 228
