<span>The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation.</span>
<span>So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation. And since x + y = 8, you are adding the same value to each side of the first equation.</span>

Step-by-step explanation:
#Given a significance level of 
and
the critical value is,
#the margin of error can then be calculated as:
Hence the margin of error is 3.4363
The conversion of 19 pounds to grams is 8170.74 grams.
<h3>How to calculate the value?</h3>
From the information illustrated, it should be noted that it was illustrated that 1 pound = 453.93 grams.
In this case, in order to fund the value of 18 pounds, we will have to multiply 18 by 453.93 grams.
This will be calculated as:
18lb = 18 × 453.93 grams.
= 8170.74 grams
