What is 2z-28?
2z-28 = -26
How many variables are in this number 2 plus x plus y plus 6 plus z plus equals 9?
(2+x+y+6+z) += 9x,y and z are variables, there are 3.
5x minus 2z?
3xz
What is the simplified form of 2z - 14z plus 45 over 2z plus z-30?
-2z + 3
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 the answer to -9x-7y equals -2?
There are infinitely many solutions. One linear equation in two variables cannot be solved to give a single answer.
How do you do 9x plus 2y equals -11?
9x + 2y = -11 I'm sorry to say this, but it is absolutely "impossible" to figure variables out with only one equality. You need one more of that to get those two variables (if you have only one variable it is perfectly fine and you can do it)
-3 X -2Z - 7 equals?
(-3) x (-2z - 7) = 6z + 21 = 3 (2z + 7)
what is 16z-24=8(2z-3)=?
16(2z-3)
9x plus 5y equals 3550?
To solve for two unknown variables (x and y) you require two independent equations,
2z plus 9.75-7z equals -5.15?
2z+9.75-7z=-5.15
What is the LCD of 2z-4 and 2z-10?
2(z-2)(z-5)
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 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
Are x and 9x like terms?
Yes, because they both contain the variable "x". y and 9x would not be like terms because they don't have the same variable. x and 9x2 would not be like terms because the variables are not raised to the same power.
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.
How can you find the sum of 2z-20 and 3z plus 5?
Add like terms to like: (2z - 20) + (3z + 5) = (2z + 3z) + (-20 + 5) = 5z - 15 2z is shorthand for z+z, 3z is shorthand for z+z+z, so: 2z + 3z = (z+z) + (z+z+z) = z+z+z+z+z = 5z Or, to put it another way, just add the coefficients: 2z + 3z = (2+3)z = 5z.
