solve 10r + 13 = -12

To solve 10r + 13 = -12, we need to isolate the variable r.

First, let's subtract 13 from both sides:
10r + 13 - 13 = -12 - 13
10r = -25

Next, divide both sides by 10 to solve for r:
(10r)/10 = (-25)/10
r = -2.5

Therefore, the solution to 10r + 13 = -12 is r = -2.5.

To solve the equation 10r + 13 = -12, we need to isolate the variable 'r' on one side of the equation.

Step 1: Subtract 13 from both sides of the equation:
10r + 13 - 13 = -12 - 13
This simplifies to:
10r = -25

Step 2: Divide both sides of the equation by 10:
10r/10 = -25/10
Simplifying further:
r = -2.5

Therefore, the solution to the equation 10r + 13 = -12 is r = -2.5.

To solve the equation 10r + 13 = -12, follow these steps:

Step 1: Subtract 13 from both sides of the equation:
10r + 13 - 13 = -12 - 13
10r = -25

Step 2: Divide both sides of the equation by 10 to isolate the variable r:
10r/10 = -25/10
r = -2.5

Therefore, the solution to the equation 10r + 13 = -12 is r = -2.5.
