Solve the equation with steps
-1/4 (-8x-6) = -4(x-3)

Solve for x and y a x= 13.3 y= 16.7 b x= 23.3 y= 12.5 c x= 7.5 y= 16.7 d x=7.5 y= 12.5

Using only the digits 5, 6, 7, 8, how many different three digit numbers can be formed if no digit is repeated in a number?

Since we have computer algebra systems that can solve polynomial division problems for us, why is it necessary to learn how to do these things by hand?
