Determine if the statement is true or false. If a linear system has the same number of equations and variables, then it must hav

lutik1710 [3]

Answer:

False

Step-by-step explanation:

Consider the equations with the same number of equations and variables as shown below,

Case 1

$x_{1} + x_{2} = 0\\x_{1} + x_{2} = 1$

This equation has no solution because it is not possible to have two numbers that give a sum of 0 and 1 simultaneously.

Case 2

$x_{1} + x_{2} = 1\\2x_{1} + 2x_{2} = 2$

This equation has infinitely many possible solutions.

Therefore it is FALSE to say a linear system with the same number of equations and variables, must have a unique solution.

Someone plz answer these questions and label by letter

2-b=c -(13-b)=c2-b=-13+b2b=15b=15/2c=2-15/2=4/2-15/2=-11/2 C cannot be negative, so 2-b not >0 and 13-b not <0
Both 2-b and 13-b cannot be both positive and negative, because 2-b=13-b is wrong
-(2-b)=c, 13-b=c, -2+b=13-b, 2b=15, b=15/2, c=13-b=13-15/2=26/2-15/2=11/2So, finally b=15/2 and c=11/2Answer is abs(x-15/2)=11/2
