Answer:
4x + y = 7
Step-by-step explanation:
The standard form of a linear equation is: ax + by = c
That means that we have to transform our equation into that form.
The original equation is: y + 5 = -4(x-3)
and we solve it:
y + 5 = -4x + 12
We move -4x to the left so its sign be possitive
4x +y +5 = 12, we move +5 to the right
4x + y = 12 - 5 , and we simplify
