How do I solve 4x+5=12-7x

1 answer:

4 0

Hi!

<h3>We need to isolate x on one sides, and whatever we do to the equation we have to do on both sides. </h3><h3>Subtract 5 from both sides. </h3>

4x + 5 - 5 = 12 - 5 - 7x

4x = 7 - 7x

<h3>Add 7x to both sides. </h3>

4x + 7x = 7 - 7x + 7x

11x = 7

<h3>Divide by 11 on both sides</h3>

11x/11 = 7/11

<h2>The answer is x = 7/11</h2>

Hope this helps! :)
