Answer:
y = -1
Step-by-step explanation:
1y + 14 = -4y + 9
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Add 4y and subtract 14 from both sides:
1y (+4y) + 14 (-14) = -4y (+4y) + 9 (-14)
1y + 4y = 9 - 14
5y = -5
Divide 5 from both sides:
(5y)/5 = (-5)/5
y = -5/5 = -1
-1 is your answer for y.

b(20) = 60
Step-by-step explanation:
Here, given that ;
b(x) = -2(x-50)
we want to find the value of b(20)
what we need to do is to simply substitute x for 20
That will be:
b(20) = -2(20-50)
b(20) = -2(-30)
b(20) = 60
