Answer 2

Answer:

• The value of 4x + x - 2x + x - 1 is -5.

To find:

• find the value of 4x + x - 2x + x - 1?

Given:

• Equation - 4x + x - 2x + x-1
• x= -1

Solution:

➥ 4x + x - 2x + x - 1

On replacing -1 in place of x, We get :

➥ 4( -1 ) + ( -1 ) - 2( -1 ) + ( -1 ) - 1

• Remove the brackets and simplify.

➥ - 4 - 1 + 2 - 1 - 1

• Use bodmas and add all the (-) from left and right.

➥ - 5 + 2 - 2

• Do the same again.

➥ -5 + 0

• Now add.

➥ $\bf -5$

Hence, The value of 4x + x - 2x + x - 1 is -5.
