-6r-5=7-12r
I can up with r=-3. Is this correct?
That isn't my answer.
-6r-5=7-12r
-6r + 12r - 5 = 7 - 12r + 12r
6r - 5 + 5 = 7 + 5
6r = 12
r = ?
r=2
To solve the equation -6r-5=7-12r, we want to isolate the variable r on one side of the equation. Let's go step by step:
1. Start by simplifying both sides of the equation by combining like terms:
-6r - 5 = 7 - 12r
-6r + 12r = 7 +5 (note that the sign in front of each term changes when crossing the equals sign)
6r = 12
2. Next, we want to solve for r. To do that, divide both sides of the equation by the coefficient of r (which is 6).
(6r)/6 = 12/6
r = 2
So, the solution to the equation -6r-5=7-12r is r = 2, not r = -3. Therefore, your answer is incorrect.
