Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y2 of (x + y)2.
If the question was
42 + z = 46, then subtract 42 from both sides to give z = 4
6+z = 3 z = 3-6 z = -3
To solve an equation with three unknowns, x, y and z, you require 3 independent equations.
you can not solve this equation
-7
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
3z2 + 45z + 42 = 3(z2 + 15z + 14) = 3(z + 1)(z + 14).
The expression has no solution but it can be simplified to: z+6
6+z = 3 z = 3-6 z = -3
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.

z=.3
Set up the equation and solve for z: 28 + z = 56 (next, subtract 28 from each side of the equaition to solve) z = 28
-7
If your equation was written correctly your answer should be z = (23/379) The solution is as follows: 57-56-z-7 = 757z-6+4-50 -z-6=757z-52 -z-6+52=757z-52+52 -z+46=757z -z+46+z=757z+z 46=758z (46/758)=(758z)/758 (46/758)=z (23/379)=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
z + 8 - 2 is an expression, not an equation. An expression cannot be solved. At best, you can simplify it to z + 6.
