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

What is 9z plus 5z plus 6(z-3)?
It is 20z-18 when simplified
9 times z equals 135 what is z?
To find the value of z, set up the equation: 9z = 135 (then divide both sides of the equation by 9) z = 15
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
Solve for z z over 12 equals -60?
72
Which expression represents the algebraic phrase the sum of negative three-eighths and four times x minus nine times z?
It could be: -3/8+4x-9z as an algebraic expression
Z plus 8 times z minus 7?
It's 9z-7. because: you do the 8 times z first (8z) then add the z, (9z), then minus 7. 9z-7
What is 9z plus 10 equals 145?
well you should start with 9z + 10 = 145 then balance the equation by collecting like terms 9z = 145 - 10 solve 9z = 135 then divide both sides by the number next to the variable. (in this case 9) so 9z/9 = 135/9 solve z = 15
9z to the fourth power?
It is the same as: 9*z*z*z*z
Z2 plus 9z plus 18?
z2 + 9z + 18 = z2 + 6z + 3z + 18 = z(z+6) + 3(z+6) = (z+6)*(z+3)
What does 9z plus -5z equals 30 plus 1z equal?
9z-5z = 30+z 3z = 30 z = 10
What is the answer to 9z equals 5z plus 16?
The following steps lead you to the correct answer: 9z = 5z + 16 9z - 5z = 16 4z = 16 z = 4, thus the correct answer is z = 4
9z plus 8 equals 3z-10?
9z+8 = 3z-10 9z-3z = -10-8 6z = -18 z = -3
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
4z plus 5 z equals what?
9z
How do you solve z plus 7 -14?
-7
What is the answer to -44-9z equals -31-3z?
The "answer" is the number that 'z' must be in order to make the statement true.Here's a systematic procedure to find out what the number is:-44 - 9z = -31 - 3zAdd 31 to each side of the equation:-13 - 9z = -3zAdd 9z to each side:-13 = 6zDivide each side by 6 :-13/6 = z
What is 9z plus 5z plus 6(z-3)?
It is 20z-18 when simplified
