let the cost of ball pen is " x " and the cost of fountain pen is " y "
according to question,
x = y - 5
x - y = - 5
x - y + 5 = 0
hence the linear equation with two variables
x - y + 5 = 0
according to question,
x = y - 5
x - y = - 5
x - y + 5 = 0
hence the linear equation with two variables
x - y + 5 = 0
x - y + 5 is also right
Let the cost of the pen be x.
Let the cost of the fountain pen be x.
So, according to the question, the cost of the ball pen must be 5 less than x.
bro. see question they asked equation with two variables ,but not only only a equation of one variable .so thats why i usded two variables x and y .
So, cost of the ball pen= x-5
Okay bro, so the linear equation will be= y(ball pen)= x-5
bro. why you not yielding , in question i take cost of fountain is x , thats why i choosed cost of ball pen is y so equation is x = y - 5. , both are right , you are also right because you take cost of ball pen = y but i take it = x , both are Right , you cound choose any variable
i choosed cost of ball pen is x and you choosed it y
okay
