Question

Simplify 3j - {2k - [5h - (3j + k)]}. -3h - 5k 3h - 5k 5h - 3k -5h - 3k

Answer 1

$3j - [2k - [5h - (3j + k)]]\\\\3j -[2k-[5h-3j-k]]\\\\3j-[2k-5h+3j+k]\\\\3j-[3k-5h+3j]\\\\3j-3k+5h-3j\\\\-3k+5h\\\\\boxed{\bf{5h-3k}}$

Answer 2

Answer:

The given expression $3j-\{2k-[5h-(3j+k)]\}$ is $5h-3k$

Step-by-step explanation:

Given expression, $3j - \{2k - [5h - (3j + k)]\}$

We are required to simplify the above expression.

Consider the given expression, $3j - \{2k - [5h - (3j + k)]\}$

Removing brackets one by one,

Firts we remove round brackets, we get,

$\Rightarrow 3j - \{2k - [5h - (3j + k)]\}=3j-\{2k-[5h-3j-k]\}$

Again removing square brackets, we get,

$\Rightarrow 3j-\{2k-[5h-3j-k]\}=3j-\{2k-5h+3j+k\}$

Now removing curly brackets, we get,

$\Rightarrow 3j-2k+5h-3j-k$

Now solving , we get,

$\Rightarrow 3j-2k+5h-3j-k=-3k+5h$

Thus, the given expression $3j-\{2k-[5h-(3j+k)]\}$ is $5h-3k$
