Question

5(x + 2) + 4(x - 3) + 3(x - 4)

simplify:​

Answer 1

Answer:

Answer is 12x-24

But if you want value of x

Answer is x=2

Step-by-step explanation:

5(x+2)+4(x-3)+3(x-4)

=5x+10+4x-12+3x-12

=5x+4x+3x+10-12-12

=12x+10-24

=12x-24

Or12x=24

x=24/12=2

Answer 2

Answer:

Step-by-step explanation:

Given,

5 ( x + 2 ) + 4 ( x - 3 ) + 3 ( x - 4 )

= [ (5 × x ) + (5 × 2) ] + [ (4 × x ) - (4 × 3) ] + [ ( 3 × x ) - ( 3 × 4 ) ] (∵ + × - = - )

= [ ( 5x + 10 )] + [ (4x - 12 )] + [ ( 3x - 12 ) ]

= 5x + 10 + 4x - 12 + 3x - 12 (∵ + × - = - )

= 5x + 4x + 3x + 10 - 12 - 12

= (5 + 4 + 3) x + 10 - 24 ( ∵ -12 - 12 = - 24 addition,but same sign is come " - " )

= 12x - 14 is the answer. ( ∵ -24 + 10 = -14 ,subtraction )
