Answer: x = 2, y = -2
Step-by-step explanation:
Subtract the two equations:
3x+y=-4......equation 1
3x-4y=6.......equation 2
5y = -10
Divide both sides by 5 to get the value of y
y = -2
Insert the value of y into equation 1 to get the value of x
3x + y = -4
3x + (-2) = -4
3x -2 = 4
3x = 4 +2
3x = 6
Divide both sides by 3 to get the value of x
x = 6/3
x = 2
Check: insert the values of x and y into equation 1
3x + y = 4
3 (2) + (-2) = 4
6 - 2= 4
