No, you did it incorrectly. The answer is y=-3
How I did this was;
2y+x=-15 x=3y
2y+3y=-15
If you multiply a whole number by a negative number you get a negative number, so I found a, number that could be multiplied into two different numbers that cloud be added together to have a sum of -15.
I really hope that made sense.

The solutions to f(x) = 64 is x = 7 and x = –7.

Solution:

Given data:

$$f(x)=x^{2}+15$ – – – – (1)

$f(x)=64$ – – – – (2)

To find the solutions to f(x) = 64.

Equate equation (1) and (2), we get

$x^2+15=64$

Subtract 15 from both sides of the equation.

$x^2+15-15=64-15$

$x^2=49$

$x^2=7^2$

Taking square root on both sides of the equation, we get

x = ±7

The solutions to f(x) = 64 is x = 7 and x = –7.
