r/5-3=2r/5+16
Please help me solve for r, I just can not seem to figure it out.
I would multiply each term by 5 to get
r - 15 = 2r + 90
Now you have a very simple equation.
Can you take it from there?
I think so...I got r=105
Watch your sign.
Should have been r = -105
Ok, thank you!
how silly of me 5x16 is 80, not 90
the correct answer is -95
To solve for r in the equation:
r/5 - 3 = 2r/5 + 16
We can start by getting rid of the fractions by multiplying every term in the equation by 5 (to eliminate the denominators).
Let's start solving it step by step:
First, multiply r/5 by 5:
(5)(r/5) - 3(5) = 2r/5(5) + 16(5)
This simplifies to:
r - 15 = 2r + 80
Next, we can move all the terms with r to one side and the constant terms to the other side of the equation.
Subtract 2r from both sides of the equation:
r - 2r - 15 = 2r - 2r + 80
Simplifying this further:
-r - 15 = 80
Now, let's isolate r by adding 15 to both sides of the equation:
-r - 15 + 15 = 80 + 15
Which becomes:
-r = 95
To solve for r, we can multiply all terms by -1 to change the sign:
(-1)(-r) = (-1)(95)
This simplifies to:
r = -95
So, the value of r that satisfies the given equation is r = -95.
