By multiplying 87 and 49
cross-multiplying
2 x 41 = 82
87 = 3yDivide each side of the equation by 3:29 = y

The nuclear equation for Francium-87 can be represented as 87/39K --> 87/38Sr + 0/+1e + v, where K represents Francium-87, Sr represents Strontium-87, e represents an electron, and v represents an antineutrino. This equation shows the beta decay process where a neutron is converted into a proton, releasing an electron and an antineutrino.
Reciprocal. Except that dividing by a rational equation is much easier.
2 x 41 = 82
this is an example of β radiation, n -> p + e Rb-87 -> Sr-87 + e (rem to write atomic numbers in, Rb is 37 and Sr is 38) The halflife 87Rb is 4,88.1010 years.
87 = 3yDivide each side of the equation by 3:29 = y
When you multiply both sides by a negative number the inequality must be flipped over. You do not do that when multiplying by a positive number.
Any equation that requires division by four ninths.
That means that multiplying both sides of the equation by the same non-zero number is a valid operation, which often helps you simplify the equation.
By itself there is none. A coefficient is the multiplying factor in a polynomial equation.
