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 2z-28?
2z-28 = -26
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.
What is the expression of 9x plus 4y-5 what is the sum?
The sum of the given expression would depend on the values of the variables which have not been given.
How do you factor 250z4-2z?
2z(5z - 1)(25z^2 + 5z + 1)
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)
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.
-3 X -2Z - 7 equals?
(-3) x (-2z - 7) = 6z + 21 = 3 (2z + 7)
5x minus 2z?
3xz
What is the simplified form of 2z - 14z plus 45 over 2z plus z-30?
-2z + 3
what is 16z-24=8(2z-3)=?
16(2z-3)
What is y2-2zy-2y-2z-3 factored?
(1) y2-2zy-2y-2z-3 = y2 -2y (z+1) - (2z+3) Delta = [-(z+1)]2 - (- (2z+3)) = z2+2z+1+2z+3= z2+2z+4 = (z+2)2 (If used the reduced form as b=-2(z+1) is even, b'=-(z+1) and delta=b'2-ac) y=(z+1) ± (z+2) so y = 2z+3 or y =-1 So the (1) can be written (y-2z-3)(y+1)
9x plus 5y equals 3550?
To solve for two unknown variables (x and y) you require two independent equations,
