Final answer:
Zayed completed 4 objectives and Mohamed completed 10 objectives.
Step-by-step explanation:
Let x be the number of objectives completed by Zayed.
Therefore, the number of objectives completed by Mohamed is x+6.
Together, they completed 14 objectives, so we can write the equation:
x + (x+6) = 14
Combining like terms, the equation becomes:
2x + 6 = 14
Subtracting 6 from both sides of the equation:
2x = 8
Dividing both sides of the equation by 2:
x = 4
So Zayed completed 4 objectives and Mohamed completed 4 + 6 = 10 objectives.
