A + B + C = 180
<span>C = 180 - A - B </span>
Answer:0=12
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:
3x-7=3x-5
Combine like terms:
3x-3x=7+5
0=12
Answer:
a = -19
b = -35
c = -180
d = -81
Step-by-step explanation:
