Consider this system of equations.



p=2np=2np=2n

p−5=1.5np−5=1.5np−5=1.5n



What value of nnn makes the system of equations true?

Sagot :

The values of n and p which makes the system of equations true are 10 and 20 respectively.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have system of equation:

p=2n  and

p−5=1.5n

Put p = 2n in the other equation.

2n - 5 = 1.5n

2n = 1.5n +5    (add 5 on both sides)

0.5n = 5           (subtract 1.5n on both sides)

n = 10              (divide by 0.5 on both sides)

Put n = 10 in the equation p = 2n

p = 2(10) = 20

Thus, the values of n and p which makes the system of equations true are 10 and 20 respectively.
