Question

True OR False
------------------------
y + 15 = 30, y = 20? ​

Answer 1

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \:False$

____________________________________

$\large \tt Solution \: :$

$\qquad \tt \rightarrow \: y + 15 = 30$

[ subtract 15 on both sides ]

$\qquad \tt \rightarrow \: y + 15 - 15 = 30 - 15$

$\qquad \tt \rightarrow \: y = 15$

Here, actual value of y is not the same as it is in statement, so the statement is wrong.
