N+d=47
5n+10d=295
divide 2nd by 5

n+2d=59

we have
n+d=47
n+2d=59
eliminate n
multiply first equaton by -1 and add to other equaton
-n-d=-47
<u>n+2d=59 +</u>
0n+1d=12

d=12
sub back

n+d=47
n+12=47
minus 12 both sides
n=35

Alika [10]

Answer:

The Original length of the wire is 61.1 cm.

Step-by-step explanation:

Given:

$l-12.5=48.6$

Now it has been given that the above equation can be used to find the original length in centimeters of a wire before it was cut.

Also We need to find the original length of the wire.

From above equation we can say that;

l ⇒ Original length of the wire.

On Solving the above equation we get;

$l-12.5=48.6$

Now we will add both side by 12.5 using addition property of equality.

$l-12.5+12.5 =48.6+12.5\\\\l =61.1\ cm$

Hence the Original length of the wire is 61.1 cm.
