Answer:
-10y + 18 = -3 (5y - 7) + 5y
-10y + 18 = -18y + 21 + 5y
-10y + 18 = -13y + 21
Step-by-step explanation:
-10y + 18 = -3 (5y - 7) + 5y
-10y + 18 = -18y + 21 + 5y
-10y + 18 = -13y + 21
(2x + 3) + (x+1) + (3x-10) = 180
6x - 6 = 180
6x = 186
x= 31
To solve for C, you have to get both of the numbers with a C on the same side. So, subtract the 5c from the right side onto the left side.

Then, divide by 3 on each side.

So, c = 7.
No, the sum of the lengths of any two sides must be greater than the length of the third side
