x-y=6
x=y+2
Substitute y+2 for x in the 1st equation:
(y+2) - y = 6
2=6
Since this is false, there is no answer (the two lines are parallel)
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
The solution is (x, y, z) = (2.5, 1, 2.5).
6x = 1 x = 1/6
(x, y) = (-6, 0)
Solution: 2x + 6 = 2 2x = -4 x = -2 Check: LHS = 2*(-2) + 6 = -4 + 6 = 2 = RHS
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
The solution is (x, y, z) = (2.5, 1, 2.5).
No.
6x = 1 x = 1/6
{-1,-2}
This equation is not possible. Two plus three plus four plus five does not equal 287. The system has no solution.
(x, y) = (-6, 0)
2 plus 2 equals 4plus1 equals 5minus 1 equals 4divided by 2 equals 2plus 8 equals 1010 minus 6 equals 4so it all equals to +_____29so its 29 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Solution: 2x + 6 = 2 2x = -4 x = -2 Check: LHS = 2*(-2) + 6 = -4 + 6 = 2 = RHS
Y=-6
X = 6
y = 6
