Answer:
<h2>x = 3.1</h2>
Step-by-step explanation:
<h3>

</h3>
<u>To solve first take logarithm to both sides</u>
That's
<h3>

</h3><h3 /><h3>

</h3>
But
<h3>

</h3>
So we have

<u>Write 1200 as a number with the factor 100</u>
That's
1200 = 100 × 12
So we have
<h3>

</h3>
<u>Using the rules of logarithms</u>
That's
<h3>

</h3>
Rewrite the expression
That's
<h3>

</h3><h3 /><h3>

</h3><h3>

</h3><h3>

</h3><h3 /><h3>

</h3>
x = 3.079
So we have the final answer as
<h3>x = 3.1 to one decimal place</h3>
Hope this helps you
Answer:

Step-by-step explanation:
From the question we are told that
System of equations given as
x₁ + 3x₂ + x₃ + x₄ = 3;
2x₁ - 2x₂ + x₃ + 2x₄ = 8;
x₁ - 5x₂ + x₄ = 5
Matrix form

Generally the echelon reduction is mathematically applied as

Add -2 times the 1st row to the 2nd row

Multiply the 2nd row by -1/8

Add -1 times the 2nd row to the 3rd row

Multiply the 3rd row by -8/41

Add -1/8 times the 3rd row to the 2nd row
Add -1 times the 3rd row to the 1st row

Add -3 times the 2nd row to the 1st row
