Question

solve the equation 4y + 4/5, is equal to 21​

Answer 1

Answer: y = 5.05

Step-by-step explanation: To find y we must simplify the equation until we have y on one side, and a number on the other side.

As this is an equation we do this to both sides to keep it a balanced equation.

4y + 4/5 = 21

times by 5:  20y + 4 = 105

-4:  20y = 101

divide by 20:  y = 5.05

So the answer is y = 5.05

Hope this helps.
