A linear equation simply means there are no squared's or cubed's or any other nasty bits in it. It could look like this:
15x + 19 = 49
To solve this, you subtract 19 from both sides to give:
15x = 30
Then divide both sides by 15 so you find x = 2
You can sometimes find an equation with two variables in it such as 4x + 5y = 100. However you cant find two variables form one equation, you need two and this is called simultaneous equations.
On the secondary problem, such as 4x + 5y = 100, you can use the substitution method.
It involves setting the x to zero and solving, and then setting y to zero and solving.
Let's solve for "y":
- 4(0) + 5y = 100
- 5y = 100
- 5y/5 = 100/5
- y = 20
Therefore the ordered pair is (0, 20)
Let's solve for "x":
- 4x + 5(0) = 100
- 4x = 100
- 4x/4 = 100/4
- x = 25
Therefore the ordered pair is: (25, 0)
