<span> Abby method
1)2x
2)2x-20%------> 2x-0.4x
</span>algebraic expression<span>-----> [2x-0.4x]---------> 1.6x
</span> Renato method
1)x/5
2)(x/5)*8-------> 8x/5
algebraic expression----->[8x/5]---------------> 1.6x<span>
Part B)
</span>[2x-0.4x]=[8x/5]---------> 1.6x=8x/5--------> 5*(1.6x)=8x-------> 8x=8x
therefore
<span>the two methods give the same answer
the answer is 1.6x</span>
