Answer:
A ) subtract the second equation from the first equation
Step-by-step explanation:
2x + 3y = 7
2x - 4y = -5
subtracting the second equation from the first equation we get,
7y = 12
y=12/7
This is the correct option
Let's consider the following system of equations.
2x = 4y - 5
If we subtract the second equation from the first equation, we get:
2x + 3y - 2x = 7 - (4y - 5)
3y = 7 - 4y + 5
y = 12/7
Then, we can use any of the original equations and solve for x.
2x = 4(12/7) - 5
x = 13/14
