The interpretation of 0 = -12 is (a) There are no solutions to the system because the equations represent parallel lines.
<h3>How to interpret the result?</h3>
The result is given as:
0 = -12
By comparison 0 and -12 do not have the same value
i.e. 0 ≠ - 12
This means that the system of equation has no solution
Hence, the interpretation of 0 = -12 is (a)

Joanna bought 7 notebooks and 14 pencils
Step-by-step explanation:
Step 1 :
Let x denote the number of notebooks and y denote the number of pencils Joanna bought.
Cost of one notebook = $ 2.30
Cost of one pencil = $1.42
Step 2 :
Total of notebooks and pencils bought = 21
=> x + y = 21 => y = 21-x
Total cost of notebooks and pencils = $35.98
=> 2.3x + 1.42y = 35.98
Substituting y = 21- x here , we have,
2.3x + 1.42 ( 21-x) = 35.98
2.3x + 29.82 - 1.42x = 35.98
0.88 x = 6.16
=> x = 7
y = 21-x = 21-7 = 14
Step 3 :
Answer :
