Answer:
<em><u>x=-2</u></em>
Step-by-step explanation:
<u>Let's solve your equation step-by-step.
</u>
<em>3x+9=x+5
</em>
<u>Step 1: Subtract x from both sides.
</u>
<em>3x+9−x=x+5−x
</em>
<em>2x+9=5
</em>
<u>Step 2: Subtract 9 from both sides.
</u>
<em>2x+9−9=5−9
</em>
<em>2x=−4
</em>
<u>Step 3: Divide both sides by 2.
</u>
<em>2x
/2=-4/2</em>
<em>x=−2
</em>
