Question

In order to solve for the variable In the equation 1-(x+2)+2x=5(2x-5)-x, Mikel first applies the distributive property. Which equation is a result of this step? A)1-x+2+2x=10x-5-x B)1-x-2+2x=10x-25-x C)1-x-1+2x=10x-25-x D)1-x-1+2x=10x-5-x

Answer 1

distributive property is a(b+c)=ab+ac

so

-(x+2)=-1(x+2)=-1(x)-1(2)=-x-2

5(2x-5)=5(2x)+5(-5)=10x-25

you get

1-x-2+2x=10x-25-x

answer is B
