Question

solve: 9x + 7 - 5x = 4x - 7

Explanation:

Step1: Combine like - terms on the left - hand side

Combine $9x$ and $-5x$ in $9x + 7-5x$. We get $(9x-5x)+7=4x + 7$. So the equation becomes $4x + 7=4x-7$.

Step2: Subtract $4x$ from both sides

$4x+7-4x=4x - 7-4x$.
This simplifies to $7=-7$.
Since $7
eq - 7$, there are no solutions.

Answer:

no solutions
