Answer:

True

Step-by-step explanation:

A linear system of equations will have a unique solution if and only if the number of variables equal the number of independent equations.

By independent equations we mean the same equation not repeated by multiplying by any constant.

Suppose number of variables are n, we must have the determinant formed by the coefficients non zero to have a unique solutions.

Here the no of equations are less than the number of variables.  So we cannot have a unique solution but can have a parametric solution using the number of parameters as n-m where n = number of variables and m = the number of independent equations given.

So the given statement is true.

if a box of pen given 200 children each will get to Pen if the number of children is reduced by 10 how many pens would each get​
wlad13 [49]

Answer:

20

So origianally, a box of 200 pens gave 2 each to every child. IThat means that there were 100 kids origianally. How? 200/2=100.

If they reduced it by 10, then 100/10=10.

200 / 10 = 20.

So each child would get 20 pens!
