Verify each of the solutions by substituting them back into the original equation <span><span>log<span>(−2a+9)</span>=log<span>(7−4a)</span></span><span>log<span>(-2a+9)</span>=log<span>(7-4a)</span></span></span> and solving. In this case, all solutions were found to be valid.<span>a=−<span>1</span></span>
So, this is -4 * 5 * -1 * -2
this is -20 * 2
total is -40
Hope this helps :)
Each family brought 11 chairs. You would just subtract 5 from 49 and divide it by 4 to get 11.
