Question

Find the missing number so that the equation has no solutions. __x+ 3 = 5x+19

Answer 1

Answer:

5

Step-by-step explanation:

The given equation is:__x+ 3 = 5x+19

Let the missing number be k, then

$kx + 3 = 5x + 19$

Combine like terms to get:

$kx - 5x = 19 - 3$

$(k - 5)x = 16$

For the equation to have no solution, the coefficient of x must be zero.

$k - 5 = 0$

$k = 5$

Therefore the missing number is 5
