[tex]4(5x+7)--3(4x-1)=32x+25[/tex]






EXPLANATION

Note that the expression which comes immediately after from comes first.


[tex]4(5x+7)--3(4x-1)[/tex]



We convert the minus minus to plus



[tex]4(5x+7)--3(4x-1)=4(5x+7)+3(4x-1)[/tex]




We expand to obtain,


[tex]4(5x+7)--3(4x-1)=20x+28+12x-3)[/tex]



We group like terms to obtain,


[tex]4(5x+7)--3(4x-1)=20x+12x+28-3[/tex]



We simplify to obtain,



[tex]4(5x+7)--3(4x-1)=32x+25[/tex]
