The equation 7 x + 14 y + 10 z = 98001 has infinite solutions. For any x and y we can have a z which satisfies this equation. For example, if we choose x=1 and y=1 then z=9798 satisfies. To have a specific solution there must be three equations for three unknowns (x,y,z), which can be solved simultaneously.
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
6z-4z-z = 6-7-4 z = -5
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
(7z - 4)(4z - 7) so z = 4/7 or 7/4
5z2-33z-14 = 0 (5z + 2)(z - 7) = 0 {factored into two binomials} 5z + 2 = 0 or z - 7 = 0 {set each factor equal to 0} 5z = -2 or z = 7 {subtracted 2 and added 7, respectively} z = -2/5 or z = 7 {divided left equation by 5}
Without an equality sign and not knowing the plus or minus value of 81 it can't be solved. If you mean: z+81 = 9z-7 Then: z-9z = -7-81 => -8z = -88 By dividing both sides by -8: z = 11

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.
