Question

in the equation x + 19 = 10; what is the constant

Answer 1

Answer:

x = (-9)

Therefore, (+ve) + (+ve) = (+ve).

(-ve) + (-ve) = (-ve).

(+ve) - (+ve) = (+ve).

(-ve) - (-ve) = (-ve).

(+ve) + (-ve) = The smaller number subtracting by bigger number.

(-ve) + (+ve) = The smaller number subtracting by bigger number.

(+ve) - (-ve) = (+ve)

(-ve) - (+ve) = (-ve)

So, x + 19 = 10

(-9) + 19 = 10
