Question

A linear equation is given which says $4m+5=25$. To balance this, which numbers should be added in the blanks respectively?

$4m+5+\text{\_\_\_}=25+\text{\_\_\_}$

• A. $+25,-25$
• B. $+5,-5$
• C. $-5,+5$
• D. $-5,-5$

Answer 1

The correct option is D $-5,-5$

To balance an equation, numbers added on both sides should be equal and have the same sign.

Therefore, $4m+5=25$ is balanced as
$4m+5+(-5)=25+(-5)$
