y - 4.6= 12
What is the answer

y-4.6=12

We simplify the equation to the form, which is simple to understand  

y-4.6=12

We move all terms containing y to the left and all other terms to the right.  

+1y=+12+4.6

We simplify left and right side of the equation.  

+1y=+16.6

We divide both sides of the equation by 1 to get y.  

y=16.6

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
