Question

Solve for x. -5x = -10 x = 2 x = -2 x = 50

Answer 1

Answer:

Putting x= 2

$( - 5) \times 2 = - 10 \\ - 10 = - 10$

putting x = -2

$( - 5) \times ( - 2) = - 10 \\ 5 \times 2 = - 10 \\ 10 = - 10 \\ this \: is \: not \: correct \: equation$

putting x = 50

$( - 5) \times 50 = - 10 \\ - 250 = - 10 \\ this \: is \: also \: not \: correct \: equation$

so, x = 2 is applicable.
