D is the answer good lick but i’m pretty sure solving it
The y-coordinate of this solution is -3 using simultneuos equation.
What is simultaneous equation?
Simultaneous equations may be used while considering the relationship between the charge of a commodity and the portions of the commodity humans need to buy at a certain price. An equation can be written that describes the connection among quantity, charge and other variables, such as earnings.
The elimination method is in which you clearly get rid of one of the variables with the aid of adding the two equations. on this manner, you take away one variable so that you can remedy for the alternative variable. In a -equation gadget, considering you have variables, putting off one makes the system of fixing for the other pretty clean.
Step 1: Multiply every equation by means of a appropriate number so that the 2 equations have the equal leading coefficient.
Step 2: Subtract the second one equation from the first.
Step three: remedy this new equation for y.
Step 4: replacement y = 2 into either Equation 1 or Equation 2 above and clear up for x.
Solving;
2x+y=7
-3x+y=2
__________ SOLVING
X+0 =5
therefore X= 5
putting the value of X in equation 2x+y=7
⇒ 2x+y=7
⇒ y = 7 - 2*5
⇒ y = 7 -10
⇒ y = -3
Hence, the answer is option A
