Final answer:
Using elimination method, the system of equations 2x + 3y = 10 and 4x - 2y = 5 is solved to find that x = 5/4 and y = 15/8. None of the provided options match this solution.
Step-by-step explanation:
To solve the given pair of equations 2x + 3y = 10 and 4x - 2y = 5 for x and y, we can use the method of substitution or elimination. For the purpose of this explanation, let's use the elimination method.
- Multiply the first equation by 2, to make the coefficient of y in both equations the same with opposite signs. This gives us 4x + 6y = 20.
- Now, subtract the second given equation from the new equation we just formed. This will eliminate y and give us 4x + 6y - (4x - 2y) = 20 - 5, which simplifies to 8y = 15. Thus, y = 15/8.
- Substitute the value of y back into the first given equation to find x. This will give us 2x + 3(15/8) = 10, which simplifies to x = 5/4.
The solution to the system of equations is x = 5/4 and y = 15/8. None of the options provided (a, b, c, d) are correct.
