-3 X -2Z - 7 equals?
(-3) x (-2z - 7) = 6z + 21 = 3 (2z + 7)
How do you solve the equation 51 2z 8z equals 23?
By including its plus or minus signs
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)
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
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
Ifx equals y equals 2z then what is the value of x?
y and ½z
What is the absolute value of 2z-3 equals 0?
2z-3 equalls 0 and 2z equalls 3 and z equalls 3/2 therefore z = 1.5
What is the only value z for which 6z - 24 equals 2z plus 50?
z = 18.5 6z - 24 = 2z + 50 Take the -24 to the other side of the equals and change its sign; take the 2z to the other side of the equals and change its sign: => 6z - 2z = 50 + 24 => 4z = 74 Divide both sides by 4: => z = 18.5
What is the value for z for which z over 3 plus 3 equals 2z - 3?
z = 3.6
-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
What Given that x equals 6 is solution to 5jx plus z equals 3 evalutate the expression 60j plus 2z?
60j + 2z = 6
What is 2z plus 17 equals 21?
2z+17=21 subtract 17 from both sides. 2z=4 divide both sides by 2 z=2
What is 2z 9.75-7z-5.15?
The answer to 2Z plus 9.75 subtract 7Z subtract equals 14.90. This is a math problem.
What is the solution to 2z-7 equals 13?
2z-7=13 +7 +7 add 7 to each side2z=20/2 /2 divide each side by 2z=10 is your answer
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
What is the answer to -8 equals 2z equals 4?
There can't be any answer to it, because the question itself is nonsense. You're saying that ' -8 ' and ' 4 ' are both equal to ' 2z '. If that's true, then ' -8 ' has to be equal to ' 4 '. Do you see the problem ?
