Question 49

Answer True/False.

$a=3$ is a solution of the equation $2a-1=5$.

Answer 1

True.

Given equation is $2a-1=5$.

Adding 1 to both sides of the equation, we get

$2a-1+1=5+1$

$\Rightarrow$$2a=6$.

Dividing both sides of the equation by 2, we get

$\Rightarrow$ $\frac{2a}{2}=\frac{6}{2}$

$\Rightarrow a=3$

$\therefore a=3$ is the solution of the given equation.
