-3 X -2Z - 7 equals?
(-3) x (-2z - 7) = 6z + 21 = 3 (2z + 7)
Which classifaction best describes the following system of equations x-y-z equals 0 2x-y plus 2z equals 1 x-y plus z equals -2 is it consistent incosistnet dependent or independent?
1st equation: x-y-z = 0 2nd equation: 2x-y+2z = 1 3rd equation: x-y+z = -2 They appear to be simultaneous equations dependent on each other for the solutions which are: x = 4, y = 5 and z = -1
If x equals y equals 2z and xyz equals 256 then what is the value of x?
8
Solve the following system of equations x plus 2y -6 equals z 3y-2z equals 7 4 plus 3x equals 2y -5z?
x+2y-6=z -z -z x+2y-z-6=0 +6 +6 ---------> x+2y-z=6 3y-2z=7 ---------> 0x+3y-2z=7 4+3x=2y-5z -3x -3x ---------> -3x+2y-5z=4 Put them into a matrix, for x,y,z and their answers. Solve for [A]-1[B], and the answer comes to: x= 1.75, y= 1.5, and z= -1.25
Use the Gauss-Jordan method to solve the equation 3x-5y-2z -9 -4x plus 3y plus z 11 8x-5y plus 4z 6?
Without an equality sign the given terms can't be considered to be an equation.
How do you solve 4z plus 3 equals 6 plus 2z?
4z + 3 = 6 + 2zSubtract 2z from each side of the equation:2z + 3 = 6Subtract 3 from each side:2z = 3Divide each side by 2:z = 3/2 = 1.5
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.
Solve the equation z2 plus 6z plus 24 equals 0?
2z+6z+24=0 8z+24=0 8z= -24 z= - 3
How do you solve the equation. X2 plus y2 plus z2 - 4x plus 4y plus 2z plus 5 equals 0 x2 plus y2 plus z2 equals 4?
(2-r)e-rr
How do you solve 2 z -5 equals 11?
2z - 5 = 11 Add 5 to both sides: 2z = 16 Divide both sides by 2: z = 8
The equation of the yz-trace is y plus 2z equals 4 for which plane?
3x 3y + 6z = 12
How do you solve 9-4z2?
You cannot solve this statment as there is nothing to equate to it. However, it will factor. 9 - 4z^2 First we note that both '9' and '4' are squared numbers. 9 = 3^(2) & 4 = 2^(2) So we can re-write the statement as 3^(2) - (2z)^(2) Note that it now has two squared terms with a negative between them . This will factor to 3^(2) = (2z)^2 = ( 3 - 2z_)(3 + 2z) NOTE the different signs. NB Two squared terms with a positive(+) between them will NOT factor.
What are the intercepts of the equation 4x plus 6y plus 2z equals 12?
x=3 y=2 z=6
-3 X -2Z - 7 equals?
(-3) x (-2z - 7) = 6z + 21 = 3 (2z + 7)
2z plus 9.75-7z equals -5.15?
2z+9.75-7z=-5.15
Solve the system of equations 3x - y 4z 9 2x 3y - 2z 16 4x - 3y z 1?
post an equation first.
How do you solve 9z plus 10-6z equals 7 plus 2z-3?
9z + 10 - 6z = 7 + 2z - 3 gather together z terms on the left 3z + 10 = 7 + 2z - 3 gather integers on the right 3z + 10 = 2z + 4 subtract 2z from each side z + 10 = 4 subtract 10 from each side z = - 6 ----------------check in original equation 9(- 6) + 10 - 6(- 6) = 7 + 2(- 6) - 3 - 54 + 10 + 36 = 7 - 12 - 3 - 8 = - 8 --------------checks
