We use the distributive property
[tex]5x+5-2x+11[/tex]Then, we reduce like terms.
[tex]3x+16[/tex]Therefore, expression A is equivalent to expression 4.
Expression B is[tex]2x+2+x+5[/tex]We reduce like terms
[tex]3x+7[/tex]Therefore, expression B is equivalent to 2 because
[tex]\frac{1}{2}(6x+14)=3x+7[/tex]Expression C is[tex]\frac{-3}{8}x-9+\frac{5}{8}x+1[/tex]We reduce like terms
[tex]\frac{-3x+5x}{8}-8=\frac{2x}{8}-8=\frac{x}{4}-8[/tex]Therefore, expression C is equivalent to expression 1.
Expression D is [tex]2.06x-5.53+4.98-9.02[/tex]We know that
[tex]2.06x+(-5.53)+4.98+(-9.02)=2.06x-5.53+4.98-9.02[/tex]Therefore, expression D is equivalent to expression 5.
Expression E is[tex]99x+44[/tex]If we express each number as factors, we have
[tex]99x+44=11\cdot9x+11\cdot4=11(9x+4)[/tex]Therefore, expression E is equivalent to expression 3.
