Step-by-step explanation:
Answer:
B.
Step-by-step explanation:
Consider the system of three equations:
Multiply the first equation by 5, the second equation by 2 and subtract them:
Multiply the first equation by 3, the second equation by 2 and subtract them:
Multiply the third equation by 2 and add the second and the third equations:
Fro mthe third equation
Substitute it into the second equation:
Substitute y=20 and z=-14 into the first equation:
The solution is
Answer:
1/3x=14
answer for x is 42
Step-by-step explanation:
x represents the original number and 1/3 of the number equals 14. So 1/3x=14
So therefore 1/3x=14 which x = 42 in case if you were wondering.
