Question

Solve the equation $5x=7.5$ by the systematic method.

Answer 1

Solving the equation by Systematic Method

According to the rules for solving an equation by systematic method.

If we divide both the sides of the equation by same non-zero quantity, the equality remains unchanged ,i.e, if $x=a$, then $\frac{x}{m}=\frac{a}{m}$.

We have the equation $5x=7.5$

$\Rightarrow$ $5x=7.5$

$\Rightarrow$ $\frac{5x}{5}=\frac{7.5}{5}$ [Dividing by $5$ on both sides of the equation ]

$\Rightarrow$ $x=1.5$

$\therefore$ $x=1.5$ is the solution of the equation

Hence the solution of the equation $5x=7.5$ is $x=1.5$
