Answer:
<h3>The question, </h3>
,
<h3>Let me explain, </h3>
<h3>For infinity many solutions </h3>
They must be parallel to each other,
For instance,
If 4x - 2y = - 2 is the equation then,
<h3>Another equation be 4x - 2y +k = </h3>
Where k can be any numerical value.
<h3 />
2x because its 2 times the price of the book (x)
When you write it as an inequality you get x + 19 ≈ 8.2 and when you solve it it should look like x + 19 ≈ 8.2
19 ≈ - <u>19
</u> x ≈ -10.8<u>
