Answer:
The solution is
Step-by-step explanation:
You are given the system of three equations:
Multiply the first equation by 4, the second equation by 3 and subtract them. Then multiply the third equation by 2 and subtract it from the second equation:
So,
Multiply the third equation by 23 and subtract it from the second equation:
Hence,
Substitute it into the second equation:
Substitute them into the first equation:
The solution is
If it is in the form of y=mx+b then the answer would be y=34x+60
Answer:
19
Step-by-step explanation:
19 x 2 = 38
Twice a quantity usually indicates to take two of the things in question; usually this indicates to multiply by 2. Thus "twice a number x" can be written symbolically as 2x. If this is part of a problem, say twice a number x is 6, then we can rewrite algebraically as 2x=6; dividing both sides by 2 yields x=3.
