Step-by-step explanation:
180-108=72+120=192,360-192=168
Answer:
x<9
Step-by-step explanation:
9514 1404 393
Answer:
no solution
Step-by-step explanation:
The equations are inconsistent. The set of equations reduces to ...
x + 2y + 3z = 12
x + 2y + 3z = 30
x + 2y + 3z = 60
No values of x, y, and z can satisfy all three equations. There is no solution.
10^4 = 10,000
9 x 10,000 = 90,000
