Answer:
x + y = 36.....Equation 1
x = 7 + 2y...... Equation 2
Step-by-step explanation:
Let the number of:
Orange goldfish = x
Black gold fish = y
Anna has a total of 36 goldfish in her aquarium, some are orange and some are black.
x + y = 36.....Equation 1
The number of orange goldfish is 7 more than twice the number of black goldfish.
x = 7 + 2y...... Equation 2
We can rewrite this as:
x - 2y = 7..... Equation 2
The system of equations below that can be used to describe the number of black and orange goldfish in Anna's aquarium is :
x + y = 36.....Equation 1
x = 7 + 2y...... Equation 2

Step-by-step explanation:
Remark
Base angles of Isosceles triangles are equal.
Equation
That means that 8x + 14 = 14x - 15
Solution
8x + 14 = 14x - 15 Add 15 to both sides
8x + 14+15 = 14x Combine
8x + 29 = 14x Subtract 8x from both sides
8x - 8x + 29 = 14x - 8x Combine
29 = 6x Divide by 6
x = 29/6
x = 4 5/6
Answer
x = 4 5/6 or 4.833
8x + 14 = 8 * (4 5/6) + 14
8x + 14 = 38 2/3 + 14
8x + 14 = 52 2/3 or 52.6666
14x - 15 = 14 *(4 5/6) - 15
14x - 15 = 67 2/3 -15
14x - 15 = 52 2/3 or 52.666
