Let's solve your equation step-by-step.<span><span><span><span>√x</span>+10</span>−9</span>=<span>−7
</span></span><span><span><span>√x</span>+1</span>=<span>−7
</span></span>Step 1: Add -1 to both sides.
<span><span><span><span>√x</span>+1</span>+<span>−1</span></span>=<span><span>−7</span>+<span>−1
</span></span></span><span><span>√x</span>=<span>−8
</span></span>Step 2: Solve Square Root.
<span><span>√x</span>=<span>−8
</span></span><span>x=<span><span>(<span>−8</span>)</span>2</span></span>(Square both sides)
<span>x=64
