5x-12=3x
Let's solve your equation step-by-step.
<span><span><span>5x</span>−12</span>=<span>3x
</span></span>Step 1: Subtract 3x from both sides.
<span><span><span><span>5x</span>−12</span>−<span>3x</span></span>=<span><span>3x</span>−<span>3x
</span></span></span><span><span><span>2x</span>−12</span>=0
</span>Step 2: Add 12 to both sides.
<span><span><span><span>2x</span>−12</span>+12</span>=<span>0+12
</span></span><span><span>2x</span>=12
</span>Step 3: Divide both sides by 2.
<span><span><span>2x/</span>2</span>=<span>12/2
</span></span><span>x=<span>6</span></span>
