Answer:
[tex]3x + 4y = -10[/tex]
Step-by-step explanation:
Given
Equation:
[tex]3x + 4y = 10[/tex]
Options:
[tex]3x + 4y = -10[/tex]
[tex]3x - 4y = 10[/tex]
[tex]3x + 4y = 10[/tex]
[tex]3x - 4y = -10[/tex]
Required
Select which option answers the question
Analyzing the options one after the other:
Option 1: [tex]3x + 4y = -10[/tex]
Represent the given equation as equation 1 and the option as equation 2;
So, we have:
[tex]3x + 4y = 10[/tex]
[tex]3x + 4y = -10[/tex]
Subtract equation 2 from 1:
[tex]3x - 3x + 4y - 4y = 10 -(-10)[/tex]
[tex]0 + 0 = 10 +10[/tex]
[tex]0 = 20[/tex]
Since,
[tex]0 \neq 20[/tex]
We can conclude that both equations has no solution
Hence:
Option 1 answers the question and there's not need to check for other options
