-6u+7=-29 what does u equal​

Answer: <em>u = 6</em>

Step-by-step explanation: To solve for <em>u</em> in the equation you see here, we must first isolate the term containing <em>u</em> which in this problem is -6u.

Since 7 is being added to -6u, we subtract 7 from both sides of the equation to isolate the -6u. On the left side of the equation, the +7 and -7 cancel out and on the right side of the equation, -29 - 7 is -36 so we have -6u = -36.

Now we can finish things off by just dividing both sides of the equation by -6. On the left the -6's cancel and on the right -36 divided by -6 is 6.

So u = 6 and you can check your answer by 6 back in for <em>u</em> in the original equation shown below in italics.

<em>-6 (6) + 7 = -29</em>
