Solve this system of equations 5x plus 3y plus z equals -29 x-3y plus 2z equals 23 14x-2y plus 3z equals -18?
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
Combine 8x plus 5z minus 4x plus 3z plus 6?
8x + 5z - 4x + 3z + 6 = 8x - 4x + 5z + 3z - 6 = 4x + 8z - 6
5x-2y plus 3z-2x-y-4z equals?
5x-2y+3z-2x-y-4z=3x-3y-z
What is the answer to x-3y plus 3z equals -4 2x plus 3y-z equals 15 4-3y-z equals 19?

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
How do you simpilify this equatoin 2x - 2y plus 5z - 2x - y plus 3z?
Add together like terms: 8z-3y
What is 1 plus 3z equals?
It equals 1 + 3z and, unless you know the value of z, you are not going to be any the wiser as to its value.
- 47 plus 6z equals 3z - 2 what does z equal?
-47 + 6z = 3z-2-3z -3z-47 + 3z = -2+47 +473z = 45/3 /3z = 15
What is the answers for 5x-2y plus 3z-2x-y plus 4z?
3x-3y+7z
What is th ordered triple of these equations x - 2y plus 3z equals -3 2x - 3y - z equals 7 3x plus y - 2z equals 6?
The ordered triple is (x, y, z) = (1, -1, -2)
What is the answer to -3z plus 17 plus 12z equals 11?
-3z+17+12z = 11 9z = -6 z = -2/3
Factorise this 8xy-12yz?
(8xy- 12yz) = 4y(2x - 3z) This is the
9z plus 8 equals 3z-10?
9z+8 = 3z-10 9z-3z = -10-8 6z = -18 z = -3
How do you solve x plus y plus z equals 7 2x plus 3y-z equals -2 5x-6x plus 3z equals 36?
Let me see:1) x + y + z = 7 y = 7 - x- z2) 2x + 3y- z = -23) -x + 3z = 36 x = 3z - 36Subst. 3) into 2):2(3z-36)+3y -z = -2Subst 1) into 3):2(3z-36) +3(7-x-z) - z = -2Subst 3) into 2) again:6z-64 + 3(7-(3z-36) - z) -z = -2z= 67/7Subst answer into 3) -x + 3(67/7) = 36x = -51/7Subst answers into 1):-51/7 + y + 67/7 = 7y = 33/7therefore x = -51/7, y = 33/7, z = 67/7
