Answer 2

★ $\textsf{\large{Answer :}}$

$\textsf{\large{The number is 6}}$

★ $\textsf{\large{Explaination}}$

• Consider the number that Penny thought as x

• The equation will be :

$\mathbf{ = > (x - 18) \div 3 = - 4}$

$\mathbf{ = > (x - 18) = - 4 \times 3}$

$\mathbf{ = > x - 18 = - 12}$

$\mathbf{ = > x = - 12 + 18}$

$\mathbf{ = > x = 6}$

$\large{\green{\boxed{\green{\boxed{\red{\textsf{x = 6}}}}}}}$

★ $\texttt{\huge{Verification}}$

Place the value of x

$\mathbf{ = > (6 - 18) \div 3 = - 4}$

$\mathbf{ = > - 12 \div 3 = - 4 }$

$\mathbf{ = > - 4 = - 4}$

$\therefore$$\textsf{\large{LHS = RHS}}$

$\therefore$$\textsf{\large{x = 6}}$

$\therefore$$\textsf{The number Penny thought was 6}$
