a)-5c2d2
b)-5cd
c)5cd
Answer:
5cd is the answer!!
3x − 2y + 2z = 2
5x − 8y − 4z = 1
Answer:
No solutions
Step-by-step explanation:
We need to eliminate one of the variables to solve the system. To do so, let's multiply the first equation by 8, the second equation by 4
The system becomes:
Add (1) and (2), subtract (3) from (2) to eliminate y
Then multiply the equation (5) by 4 to compare with(4)
Comparing the equations (4) and (5) we see it has no solutions as both variables have same coefficient but with different sum, 28≠40
