please help, I do not understand this equation or where to even start
Solve for b, then, find the value of b when a = 6. show your work
2a + 4b = 16
2a + 4b = 6
first, divide everything by 2
a + 2b = 3
Now, you subtract a and get
2b = 3-a
Finally, divide by 2 and
b = (3-a)/2
So, if a=6,
b = (3-6)/2 = -3/2
Check your answer. Does 2a+4b=6?
2(6)+4(-3/2) = 12 -6 = 6
so good.
