Question

Simplify 5 2{x - 4[3x 7(2 - x)]}. -34x - 107 34x - 107 34x 107

Answer 1

Option (b) is correct

The simplified form of given expression
`5+2\{x-4[3x+7(2-x)]\}` is 34x - 107.

Explanation:

Given expression
`5+2\{x-4[3x+7(2-x)]\}`

We have to evaluate the value of given expression

Consider the given expression
`5+2\{x-4[3x+7(2-x)]\}`

Apply PEDMAS rules,

Where P denoted parenthesis

E denotes exponents,

M denotes multiplication,

D denotes division,

A denotes addition,

S denotes subtraction.

`\Rightarrow 5+2\{x-4[3x+14-7x)]\}`

Solving further, we have,

`\Rightarrow 5+2\{x-12x-56+28x\}`

Solving further, we have,

`\Rightarrow 5+2x-24x-112+56x`

Simplify, we get,

`\Rightarrow 34x-107`

Thus, the simplified form of given expression
`5+2\{x-4[3x+7(2-x)]\}` is 34x - 107.

Answer 2

If you would like to simplify 5 + 2{x - 4[3x + 7(2 - x)]}, you can do this using the following steps:

5 + 2{x - 4[3x + 7(2 - x)]} = 5 + 2{x - 4[3x + 7 * 2 - 7x]} = 5 + 2{x - 4[-4x + 14]} = 5 + 2{x - 4 * (-4)x + (-4) * 14} = 5 + 2{x + 16x - 56} = 5 + 2x + 2 * 16x - 56 * 2 = 5 + 2x + 32x - 112 = 34x - 107

The correct result would be 34x - 107.
