Rearrange both equations into like form, by this I mean like variable should line up AND the equal marks must line up.
Add LIKE Terms only straight down keeping the equal marks in the same place.
EX
2x - 3y = 7
4x +3y = 5 Add like terms
6x = 12 ( y terms 'cancel' because there opposites)
This is usually the whole purpose, to make one variable cancel.
I made this up so that the 'y' variables would cancel. If they won't then you must find their LCM and multiply whole equations to cause them to cancel.
Ex: x + 3y = 7
2x + 5y = 12 ---- if you want 'y' to cancel 3 and 5 have a LCM of 15
make one of them become -15
5(x + 3y = 7)
-3(2x + 5y = 12)
5x + 15 y = 35
-6x - 15 y = -36 ----- now add
-1x = -1

Are linear equations and functions different?
All linear equations are functions but not all functions are linear equations.
How are linear equations and functions alike?
They are not. A vertical line is not a function so all linear equations are not functions. And all functions are not linear equations.
Are all linear equations functions Is there an instance when a linear equation is not a function?
Linear equations are always functions.
How are functions and linear equations similar?
Linear equations are a small minority of functions.
How are functions like linear equations?
Most functions are not like linear equations.
How are linear equations and functions alike and how are they different?
A linear equation is a special type of function. The majority of functions are not linear.
When can you use linear quadratic functions?
There are linear functions and there are quadratic functions but I am not aware of a linear quadratic function. It probably comes from the people who worked on the circular square.
What similarities and differences do you see between the function and linear equations?
Linear equations are a tiny subset of functions. Linear equations are simple, continuous functions.
What are non linear functions?
Functions that do not result in a line when graphed.
What are two linear functions?
y = 0 and y = 1 are two linear functions. They're not especially interesting ones.
What are linear functions?
A linear function is of the form y = ax + b
Is the sum of two linear functions also a linear function?
Yes.
