$15-3\times 4=9$

• A. $+\times =$
• B. $\times -=$
• C. $+-=$
• D. $÷+=$
• E. $+÷=$

Answer 1

The correct option is D $÷+=$

Please put the options one by one.

Option $\left(A\right)$

$15+3\times 4=9$

$⟹15+12=13$

$⟹27=13$

As $LHS\ne RHS$

Option $\left(B\right)$

$15\times 3-4=13$

$⟹45-4=13$

$⟹41=13$

$LHS\ne RHS$

Option $\left(C\right)$

$15+3-4=13$

$⟹18-4=13$

$⟹14=13$

$LHS\ne RHS$

Option $\left(D\right)$

$15÷3+4=9$

$⟹5+4=9$

$⟹9=9$

$RHS=LHS$

So, $\left(D\right)$ is the answer.
