Question 344280
Plug it into your original equation and see if it solves it.
.
.
.
Example:
{{{2x+5=3x}}}
Solution is {{{x=5}}}
Verify by plugging the solution into the equation.
{{{2(5)+5=3(5)}}}
{{{10+5=15}}}
{{{15=15}}}
True, so the solution {{{x=5}}} is a good solution.

.

How about {{{x=2}}}? Is it a solution?
{{{2x+5=3x}}}
{{{2(2)+5=3(2)}}}
{{{4+5=6}}}
{{{10=6}}}
False, so {{{x=2}}} is not a solution.
