Answer:
r > -178
Step-by-step explanation:
Solving the equations means to find what "r" can be for the equation to be true.
If the sign < confuses you, you can always write = then change it back.
To find "r", we need to isolate it. To do this, we move "r" to the left side, and every other number to the right side. When you move something to the other side, remember you need to do the reverse operation on both sides.
I want to move -195 first. The opposite is +195.
-17 < -195 - r
-17 + 195< -195 + 195- r Add 195 to both sides. 195 cancels out on the right
-17 + 195 < -r Simplify left right by add 195 to -17
178 < -r The opposite of multiply by -1 is divide by -1.
178/-1 < -r/-1 Divide both sides by -1.
178/-1 < r "r" is isolated now. Simplify left side
-178 < r Answer is found. Put variable on left side. Remember the keep the open side of the symbol facing "r".
r > -178 The solution is when "r" is greater than -178.
