Which linear equations have one solution? Check all that apply. O 5x-1 =3(r+ 11)
O 4(r-2) + 4x = 8(x-9)
O 4(–6) + 4 = 2(r- 3)
o 2(-4) = 5(r-3) + 3
O 20-1) + 3r= 5(r-2) + 3

The linear equations which have one solution are C. , D. and E. .

Step-by-step explanation:

From Algebra we know that a system of linear equation has a unique solution when the number of variables is equal to the number of equations. Now we proceed to check if each option fulfills this condition:

A. : Number of equations: 1/Number of variables: 2

B. : Number of equations: 1/Number of variables: 2

C. : Number of equations: 1/Number of variables: 1

D. : Number of equations: 1/Number of variables: 1

E. : Number of equations: 1/Number of variables: 1

The linear equations which have one solution are C. , D. and E. .

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
