Answer:
<span>−84</span>
Explanation:
Let x be the unknown number.
From the queston we can form the equation
<span><span>x<span>(−7)</span></span>−2=10</span>
Move <span>−2</span> to the right hand side
<span><span><span>x<span>(−7)</span></span>=10+2</span><span><span>x<span>(−7)</span></span>=12</span></span>
Multiply both sides by <span>−7</span> to get the unkonwn no.
<span><span><span>−7</span>⋅<span>x<span>(−7)</span></span>=12⋅<span>(−7)</span></span><span>
x=−84</span></span>
Hope this helps
