Question

Answer True/False.

$x=5$ is the solution of the equation $3x+2=20$.

Answer 1

False

Given equation is $3x+2=20$.

Subtracting 2 from both sides of the equation, we get

$3x+2-2=20-2$

$\Rightarrow$$3x=18$

Dividing both sides of this equation by 3, we get

$\frac{3x}{3}=\frac{18}{3}$

$\Rightarrow$ $x=6$

$\therefore$The solution of the given equation is $x=6$.
