The solution

You have entered [src]
-9*x + 16*y = -7
$$- 9 x + 16 y = -7$$
Detail solution
Given the linear equation:
-9*x+16*y = -7

Looking for similar summands in the left part:
-9*x + 16*y = -7

Move the summands with the other variables
from left part to right part, we given:
$$- 9 x = - 16 y - 7$$
Divide both parts of the equation by -9
x = -7 - 16*y / (-9)

We get the answer: x = 7/9 + 16*y/9
Rapid solution [src]
     7   16*re(y)   16*I*im(y)
x1 = - + -------- + ----------
     9      9           9     
$$x_{1} = \frac{16 \operatorname{re}{\left(y\right)}}{9} + \frac{16 i \operatorname{im}{\left(y\right)}}{9} + \frac{7}{9}$$
x1 = 16*re(y)/9 + 16*i*im(y)/9 + 7/9
