–8x + y = 9
The given equation is –8x + y = 9
To solve the equation -8x + y = 9, we need to isolate one variable in terms of the other.
Step 1: Move the -8x term to the other side of the equation by adding 8x to both sides:
-8x + 8x + y = 9 + 8x
Simplifying, we have:
y = 8x + 9
So the equation -8x + y = 9 can be rewritten as y = 8x + 9.
The given equation is -8x + y = 9. To understand this equation better, let's rearrange it in the standard form of a linear equation, which is Ax + By = C.
To do this, we need to transpose the terms so that the x-variable and y-variable are on one side of the equation and the constant term is on the other side.
Starting with the given equation:
-8x + y = 9
We can move the -8x term to the right side of the equation by adding 8x to both sides:
-8x + 8x + y = 9 + 8x
This simplifies to:
y = 8x + 9
Now the equation is in the standard form, where A = 8, B = 1, and C = 9.
