Question

Determine if 3 is the root of the equation 5x – 10 = 5.​

Answer 1

Root = 3

Equation 5x - 10 = 5

$\bf \implies5x - 10 = 5 \: \: \: \: \\ \\ \bf \implies 5(3) = 5 + 10 \\ \\ \bf \implies15 = 15 \: \: \: \: \: \: \: \: \: \: \: \\ \\ \bf \implies LHS = RHS$

Therefore , 3 is the root of equation 5x - 10 = 5 .
