id \(8k=20\)
Serenity1jacksonsl:
kk thx for your help
Spectrum:
so: \(8k-number=20-number\) both of the math symbols have to be the same in order for the equation to be correct, same goes with the numbers.
Spectrum:
so \(8k-4=20+4\) does not fit because one side is subtracting 4 and the other is adding 4
