7x = 3
Equations as,
An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign.
2x+y=8 .......................1
5x-y=-5 .......................2
Result when adding equations 1 and 2 =?
On adding equations 1 and 2 the y term will get canceled and the like terms will combine is add (2x and 5x ) and ( 8 and - 5) as shown below
2x + y = 8
5x - y = - 5
-------------------------------------------
7x + 0 = 3
---------------------------------------------
Therefore the results from adding the equation in this system are 7x=3.
