You have no number values there; the best I can do is tell you that c = 360-a-b-d. Since b and d are the same measure, we can rename d as b, so your equation is c=360-a-2b. But since a and c are the same, rename a as c to get an equation of c=360-c-2b. Now add c to both sides to give you 2c=360-2b and c=180-b. Can't do anything else with no values.

Answer:
Step-by-step explanation:
Given that a car mechanic rounds a car's weight to the nearest thousand
By rounding off to nearest 1000, we mean we look at the last three digits. If these digits are 500 or greater, then we round the thousands digit up, and if they are less than 500, then we round down, keeping the thousand's digit the same.
To simplify the above we can say the 100th digit if greater than or equal to 5, we round off the 1000th digit by 1 up otherwise leave it as it is
Example, 18765 is rounded off as 19000 while
15462 is rounded off as 15000
Here the answer after rounding off is 4000
This is possible if the weight was atleast 3500 because in this case he would round off to 4000 or highest 4499.
If 3499 or 4500 the rounding off would not have been 4000
So least number is 3500 and greatest number is 4499.
