Question

check whether the value given in the bracket is the root of the given equation or not​

Answer 1

Answer:

$\sf4( - 3) - 3 = - 5 \\ \sf \to - 12 - 3 = - 5 \\ \sf \to - 16 \: \not = \: - 5$

$\bf \therefore false$

__________________

$\sf7( - 2) + 5 = 19$

$\sf \to - 14 + 5 = 19$

$\sf \to - 11 \not = 19$

$\bf \therefore false$

__________________

$\sf15 = 3 - 4( - 2)$

$\sf \to15 = 3 + 8$

$\sf \to15 \not = 11$

$\bf \therefore false$

__________________

$\sf \frac{18}{6} = 3$

$\sf \to \frac{9}{3} = 3$

$\sf \to3 = 3$

$\bf \therefore true$
