Positive if the positive number is greater than the negative number. negative if the negative number is greater. 0 if the two numbers are opposites of eachother. an example of this would be -5+5
<span>y = 2x + 3
</span><span>2x - y = 7
Substituting the value of y,
2x - (2x + 3) = 7
2x - 2x - 3 = 7
-3 </span>≠ 7
Hence, there is no solution to this equation. This equation does not even exist.

shown in the attachment is how you solve it..
