Question

find the missing number so that the equation has no solutions. 5x - 7 = \square x - 9

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 for no solution

Set the coefficient of $x$ on both sides equal: $\text{Missing number} = 5$. Verify constants: $-7
eq -9$, which satisfies the no-solution condition.

Answer:

5
