Question

find the missing number so that the equation has no solutions. 3x + 2 = \square x + 12

Explanation:

Step1: Recall no-solution linear equation rule

A linear equation $ax + b = cx + d$ has no solutions if $a=c$ and $b
eq d$.

Step2: Match coefficients to find missing value

For $3x + 2 = \square x + 12$, set the $x$-coefficients equal: $\square = 3$. Here, $2
eq12$, so the equation will have no solutions.

Answer:

3
