Answer:

Solution given:

8\frac{7}{12}-3\frac{1}{3}=\frac{8*12+7}{12}-\frac{3*3+1}{3}

=\frac{103}{12}-\frac{10}{3}

taking lcm

=\frac{103-10*4}{12}=\frac{63}{12}=\frac{21}{4}=5\frac{1}{4}

Seven times a number minus the number is -48. Find the number.
irinina [24]
The answer is -8 I believe.

To put this into an equation, we get 7x-x=-48. This is equal to 6x=-48. When we divide we get -8.
