Step 1:
Write out the expression
[tex]\frac{2}{4-x}=\frac{10}{4+x},x\ne4,x\ne-4[/tex]
Step 2:
We cross-multiply, to get
[tex]2(4+x)=10(4-x)[/tex]
Step 3:
we expand the expression
[tex]8+2x=40-10x[/tex]
Step 4
We collect like terms
[tex]\begin{gathered} 2x+10x=40-8 \\ \text{ Hence, we have} \\ 12x=32 \end{gathered}[/tex][tex]undefined[/tex]
