Answer:
im sorry i dont know
Step-by-step explanation:
Well just substitute y (the first equation) into the second equation.
So
5x-4(5-3x)=-3
Then just solve the equation from there.
5x-20+12x=-3
17x=17
x=1
and if you need y, y=2
(12 - 2) * 180 = 1,800/12 = 150
(8 - 2) * 180 = 1,080/8 = 135
B. 8 sides

Step-by-step explanation:
1. Use the distributive property:


Then

2. Separate terms with m in left side and without m in right side:

This expression is false for all values of x, then the equation doesn't have solutions.
Answer: no solution
