x-y=15
To Find:
The value of x
Solution:
There are basically 4 way to solve the equation with two variables but we will solve by elimination method.
What is elimination method?
Elimination is an easy and basic way to solve a equation with 2 variable. 1st we have to make equal coefficient of any of given variable in the 2 equations by multiply or division then we add or subtract it by our choice.
So,
x+y=75
x-y=15
----------------
by adding, 2x = 90
x = 45
Hence, the required value of x is 45.
