sprry dear for posting unnessary answer

Answer 2

Given : x = 2

x+7+ 4(x - 5)

3(x + 2) + 5x - 7

6x+5(x-2)

4 (2x - 1) + 3x + 11

To Find : Value of Each expression

Solution:

x+7+ 4(x - 5)

= x + 7 + 4x - 20

= 5x - 13

= 5(2) - 13

= 10 - 13

= - 3

3(x + 2) + 5x - 7

= 3x + 6 + 5x - 7

= 8x - 1

= 8(2) - 1

= 16 - 1

= 15

6x+5(x-2)

= 6(2) + 5(2-2)

= 12 + 0

= 12

4 (2x - 1) + 3x + 11

= 8x - 4 + 3x + 11

= 11x + 7

= 11 (2) + 7

=22 + 7

= 29
