Question

4-(2x-2)-2(x+4)=-1,solve step by step

Answer 1

Answer:

x = -0.25 or $-\frac{1}{4}$.

Step-by-step explanation:

$4-(2x-2)-2(x+4)=-1$

Subtract 4 from both sides = $-(2x-2)-2(x+4)=-5$

$-(2x-2)=-2x+2$ because $-(-a)=a$.

$-2x+2-2(x+4)=-5$

$-2(x+4)=2x-8$ because $a(b+c)=ab+ac$ so $-2x+(-2)*4$ which is $-2x-2*4$ which is finally $-2x-8$ when simplified.

$-2x+2-2x-8=-5$

Simplify: $-4x-6=-5$

Add 6 to both sides: $-4x=1$.

Divide both sides by -4, $x=-\frac{1}{4}$ or -0.25.
