Question

5 (x – 4) = 7 (2x + 1)

Answer 1

Answer:

-3

Step-by-step explanation:

5x - 20 = 14x + 7

5x - 14x = 7+ 20

- 9x = 27

x = -3

Answer 2

Answer:

-3

Step-by-step explanation:

5 (x - 4) = 7 (2x + 1)

5x - 20 = 14x + 7

5x = 14x + 27

-9x = 27

x = -3

5 (-3 - 4) = 7(2(-3) + 1)

5 (-7) = 7 (-5)

-35 = -35

So, the value of x is equal to -3.
