If you want to solve the system of equations it will be:
Step 1: solve the equation for y
y= -19+7 → y= -12
Step 2: substitute y into the equation
-2x+3x(-12)=-19
Step 3: solve the equation for x
x= -17/2
Step 5: the possible solution is the order pair (x,y)
Answer: (-17/2 , -12)
C would be the correct answer
A would mean that 6=3*18, which is incorrect
B would mean that 3=6*18 which is also incorrect
C would mean that 18=6*3 which is CORRECT
D would mean that 18=6*2 which is also incorrect
Therefore, C would be the correct answer
