What else can I help you with?
Z squared equals 4z plus 21?
(z=-3) and (z=7)
What is 4z plus 2 plus 5z-3?
4z + 2 + 5z - 3 = 9z - 1
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 -x - 2y plus 4z equals 8?
To solve for 3 unknown variables you need 3 independent equations. You have only 1.
15 plus -3 divided by -6 equals?
15 plus -3 equals 12 12 divided by -6 equals -2
What is 2 plus 4z plus 6 - 9z - 5?
3-5z
3 divided by4 plus 1divided by 2 minus 2 divided by 3 equals?
3 divided by 4 plus 1 divided by 2 minus 2 divided by 3
What is the solution to 7x plus y plus z equals 6 7x plus y plus 4z equals 9 y plus x equals 6?
7x + y + z = 6 7x + y + 4z = 9 y + x = 6 Take the first two statements and subtract them. 7x + y + z = 6 7x + y + 4z = 9 _____________ 0 + 0 - 3z = -3 Therefore: z = 1 Then you are left with: 7x + y + 1 = 6 7x + y + 4 = 9 which is impossible, so this is an impossible equation.
What is the average of 3 plus 1 plus 1?
1.66666666666666666667 because 3 plus 1 plus 1 equals 5 and 5 divided by 3 equals 1.6666666666666666666.7.
What is the sq. root of 4z plus 6 minus the sq. root of z plus 3 equals 0?
To solve the equation (\sqrt{4z} + 6 - \sqrt{z + 3} = 0), first isolate the square root terms: (\sqrt{4z} + 6 = \sqrt{z + 3}). Then, square both sides to eliminate the square roots: ((\sqrt{4z} + 6)^2 = (z + 3)). This leads to a quadratic equation in terms of (z) which can be solved to find the values of (z). Finally, substitute back to check for extraneous solutions.
32 plus 45 plus 39 divided by 3 equals?
90
What is the answer to C over 3 plus 4 equals 11?
