Answer 1

Answer:

Answer:

11= EC

Step-by-step explanation:

EC = 10 + 2 x + 19

= x + 20

So 2 x + 29 - x - 20 = 0

so x + 9 = 0

x = -9.

EC = x + 20 = -9+20 = 11.

Answer 2

Answer:

Answer:

EC = 11 units

Step-by-step explanation:

first we find the value of x

10 + 2x + 19 = x + 20

2x - x = 20 - 10 - 19

x = -9

--------------------------------

check

10 + 2(-9) + 19 = -9 + 20

10 - 18 + 19 = -9 + 20

11 = 11

same value the answer is good

Now we find EC

EC = 10 + 2x + 19

EC = 10 + 2(-9) + 19 (remember PEMDAS)

EC = 10 - 18 + 19

EC = 11 units
