A). The answer is x = -4
Work:
3 - x = 11 + x
3 - x - 3 = 11 + x - 3
-x = x + 8
-x - x = x + 8 - x
-2x = 8
-2x/-2 = 8/-2
Answer: x = -4

B). The answer is x = 6
Work:
2x + 7 = 3x + 1
2x + 7 = 3x + 1 - 7
2x = 3x - 6
2x - 3x = 3x - 6 - 3x
-x = -6
-x/-1 = -6/-1
Answer x = 6

C). Answer: x = 4/3
Work:
8 - 2x = 4 + x
8 - 2x - 8 = 4 + x - 8
-2x = x - 4
-2x - x = x - 4 - x
-3x = -4
-3x/-3 = -4/-3
Answer: x = 4/3

D). Answer: x = 2
Work:
4x + 2 = 2x + 6
4x + 2 - 2 = 2x + 6 - 2
4x = 2x + 4
4x - 2x = 2x + 4 - 2x
2x = 4
2x/2 = 4/2
Answer: x = 2

The number of birds on each of the islands X and Y remains constant from year to year; however, the birds migrate between island

Tasya [4]

Answer: Option 'b' is correct.

Step-by-step explanation:

Since we have given that

Total number of birds = 14000

Let the number of birds on X be 'x'.

Let the number of birds on y be 14000-x

After one year, 20 percent of the birds on X have migrated to Y, and 15 percent of the birds on Y have migrated to X.

but The number of birds on each of the islands X and Y remains constant from year to year.

So, the equation would be

$\dfrac{20}{100}x=\dfrac{15}{100}(14000-x)\\\\0.2x=0.15(14000-x)\\\\0.2x=2100-0.15x\\\\0.20x+0.15x=2100\\\\0.35x=2100\\\\x=\dfrac{2100}{0.35}=6000$

Hence, there are 6000 birds on island X.

Hence, Option 'b' is correct.
