Acopper conducting wire measures 84 cm in length. it is cut into 2 pieces. the shorter price is 5 cm shorter than the long piece. find the final length of each piece

longer piece: 44.5

shorter piece: 39.5

Work:

let x = longer piece

let x - 5 = shorter piece

x - 5 + x = 84

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.

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.
