Step-by-step explanation:
See whenever we have two variables like x and y.
And also we have given two equations in terms of x and y.
Example: ax + by = p and cx + dy = q
In order to get the solution, we need to find the value of x and y using the given two equations.
So here what we can do is:
Consider any one equation and get x or y from that equation.
i.e consider ax + by = p or x =
Now plug value of x (or y) from the equation you have considered into the another equation.
i.e c()+dy = q
Now solve this equation to get y (or x).
and after that we can find the other variable.
The first step to solving this equation is to change the signs on both sides of the equation
y = -
x + 3
Since we don't know what x is but we do know why y is,, we will write our answer with the answer to y and x being left as undefined.
y = -x + 3, x ∈ R
