subtract 11
To find the value of r in r + 11 = -17, you should subtract 11 from both sides of the equation.
To find the value of r in the equation r + 11 = -17, you need to do the same operation to both sides of the equation. In this case, you should subtract 11 from both sides of the equation.
To find the value of r in the equation r + 11 = -17, you need to perform the same operation on both sides of the equation to maintain equality. In this case, you can find the value of r by subtracting 11 from both sides of the equation.
Here's the step-by-step process:
1. Start with the original equation: r + 11 = -17
2. To isolate the variable r, subtract 11 from both sides of the equation:
r + 11 - 11 = -17 - 11
This simplifies to: r = -28
Therefore, by subtracting 11 from both sides, you find that the value of r is -28. To verify, you can substitute this value back into the original equation and see if it holds true.
