If xy plus y equals z then x equals?
xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y
X plus y plus z squared?
If th equestion meant: (x+y+z)^2The expansion is:(x+y+z)^2= x^2+2xy+y^2+2yz+z^2+2zx
Is Z equals 1A plus 2BC plus 3D a linear programming objective function?
No. 1a and 3d are linear, but 2bc is not. ■
What is the ordered triple of x plus y plus z equals 12 and y equals 1 and x-y-z equals 0?
x + y + z = 12 y = 1 x - y - z = 0 Substitute y = 1 in the other two equations: x + 1 + z = 12 so that x + z = 11 and x - 1 - z = 0 so that x - z = 1 Add these two equations: 2x + 0z = 12 which implies that x = 6 and then x + z = 11 gives z = 5 So the solution is (x, y, z) = (6, 1, 5)
Z2 equals x2 plus y2?
What are we solving here for, Z, X, or Y?If solve for Z then the answer would be z = x + yIf solve for X then the answer would be z = z - yIf solve for Y than the answer would y = z - xHope this help.
What does this equal 6z plus 28 equals 12z plus 10?
6z + 28 = 12z + 10 18 = 6z 3 = z
How do you prove Equation -6z plus 2 equals 3z plus 4z plus 28 solved for z z equals -2?
-6z + 2 = 3z + 4z + 28 Add 6z to both sides: 2 = 3z + 4z + 28 + 6z = 28 + 13z Subtract 28 from both sides: - 26 = 13z Divide both sides by 13: -2 = z
What is the solution of equation 4 x z equals 28?
4 x z = 28 z = 28/4 z = 7
X plus y plus z equals 9 and x plus 2y plus 3z equals 23 and x plus 5y-3Z equals -7 solve for x and y and z?
Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
For x plus y plus z equals 9 2x-y-z equals -6 and x plus y-z equals 1 what is the echelon matrix?
3x + 2 = 82
What does z equal if a plus b equals c and c plus d equals g and a equals 1?
z remains undefined.
What is the solution for this linear equation x plus y plus z equals 6 x plus 2y plus z equals 7 2x plus y equals 6?
