The awnser to your question is 32 hope i helped
Take second equation here,
2x + 9 = -12
2x = -12 - 9
2x = -21
Multiply by 2,
4x = -42
Now, substitute the vaue of 4x in 1st equation,
-42 - y = 2
-y = 2 + 42
y = -44
In short, Your Answer would be -44
Hope this helps!
Equation of required line is:

Step-by-step explanation:
First of all we will convert both equations in slope-intercept form

Subtracting 5x from both sides

Subtracting 9 from both sides

The y-intercept is -9.
Other equation is:

Adding 3x on both sides

Dividing both sides by 4

As the required line has y-ntercept of line y + 5x + 9 = 0
So,
b = -9
And
The line is parallel to second line, so the slopes of both will be equal

Slope-intercept form of line is:

Putting values of b and m

Let the angke be x
Its supplementary angle = 180 - x
Given:
x = 180 - x + 86
2x = 266
x = 133⁰
The one angle = 133⁰
The other angle = 180⁰ - 133⁰ = 47⁰
