Check whether the value given in the brackets is a solution to the given equation or not.2 + 3(m – 1) = 5 (m = -2)

Answer»

Given 2 + 3(m – 1) = 5 

When m = – 2 

LHS = 2 + 3(m – 1) 

= 2 + 3(- 2 – 1) 

= 2 + 3(- 3) = 2 – 9 = – 7 

RHS = 5 

– 7 ≠ 5 

Here, LHS ≠ RHS 

So, m = – 2 is not a solution of given equation.
