Explanation
To answer this question, we have to remember that for the elimination method in a simultaneous equation, the coefficient of the variable we will like to eliminate has to be equal but opposite in sign
Thus
Given the two equations
[tex]\begin{gathered} 4x+3y=-1 \\ 3x-5y=4 \end{gathered}[/tex]
To eliminate x, we will have to
Multiply
[tex]4x+3y=-1\text{ by 3}[/tex]
And then multiply
[tex]3x-5y=4\text{ by -4}[/tex]
Finally,
[tex]\text{Add the resulting equations together}[/tex]
