Answer 1

Step-by-step explanation:

Given:

$-[x-[z+(x-z)-(z-x)-z]-x]$

To find: Simplify the expression.

Solution:

Tip: If minus sign is before bracket then all the signs under bracket will change,when bracket open.

Step 1:Open bracket in blue

$-[x-[z+(x-z)-\bold{\blue{(z-x)}}-z]-x]$

$-[x-[z+(x-z)\bold{\blue{-z+x}}-z]-x]$

Step 2:Open bracket in green

$-[x-[z+\bold{\green{(x-z)}}-(z-x)-z]-x]$

$-[x-[z+\bold{\green{x-z}}-z+x-z]-x]$

Step 3: Add similar and cancel with opposite sign

$-[x-[2x-2z]-x]$

Step 4: Open bracket in red

$-[x-\bold{\red{[2x-2z]}}-x]$

$-[x\bold{\red{-2x+2z}}-x]$

or

$-[-2x+2z]$

Step 5: Open last bracket

$2x-2z$

Final answer:

$\bold{2x-2z}$
