Step-by-step explanation:
Step-by-step explanation:
117+114= 231
360-231= 129
Now find two numbers that add up to 129
I think it's D + .2 = ? i'm not sure but it might be something like that
Next, solve as you would solve any two-step inequality. Since 2 is added to , you can get by itself on one side of the inequality by subtracting 2 from both sides. Then, to get by itself on one side of the inequality, you need to multiply both sides by 2.D
