Answer:
The system has infinite solutions
Step-by-step explanation:
For a system of two linear equations it is always true that if one equation is a linear combination of another, then the system will have infinite solutions.
Suppose we have the following system:
If there is a number n for which it is fulfilled that
Then the system has infinite solutions.
In this case the system is:
Observe that:
Then 
The system has infinite solutions
Kate: Please, for clarity, use " ^ " to denote exponentiation: 2x^2 + x − 4 = 0
And please include the instructions.
2x^2 + x − 4 = 0 can be re-written: 2(x^2 + (1/2)x - 2) = 0
Dividing both sides by 2 results in x^2 + (1/2)x - 2 = 0
Let's "complete the square:" x^2 + (1/2)x + (1/4)^2 - (1/4)^2 = 0
Then (x+(1/4))^2 = (1/4)^2
Taking the sqrt of both sides: x+1/4 = plus or minus 1/4
Solving for x: x = -1/4 plus or minus 1/4
Solving for x (continued): x = 0 and x = -1/2
Answer:
if you mean like 14/3. you would divide 14 by 3 which would give you 4 times which would equal 12 so you would have two left over that couldn't be divided by 4 and you have to keep the three so the answer would be 4 2/3. with 4 being the big number and 2/3 being the other half of the mixed fraction
