Question G)

[tex]5-3x=-x-8\\\implies 5-3x+x=-x+x-8\\\implies5-2x=-8\\\implies 5+8-2x=-8+8\\\implies13-2x=0\\\implies13-2x+2x=0+2x\\\implies13=2x\\\implies x= \frac{13}{2}[/tex]

Question H)

[tex](3x+4)(5-2x)=0 \\\implies 3x+4=0 \,\,\,ou\,\,\, 5-2x=0\\\\\\3x+4=0\\\implies x=\frac{-4}{3}\\\\5-2x=0\\\implies x=\frac{5}{2}\\\\\\Solutions :\frac{5}{2} \,\,et,\,\frac{-4}{3}[/tex]
