For the equation 4(2x-4)=8x+k, what value of K will create an equation with infinitely many solutions? Please show steps
strojnjashka [21]
If you use the distributive property, you will multiply 4 by 2x to get 8x and 4 by -4 to get -16.

8x-16=8x+k

If you want infinitely many solutions the equations on both sides of the equal sign need to be the same. So, k would need to be -16.
