What is 7 plus 4z equals 43?
7 + 4z = 437 + 4z -7 = 43 - 7 4z = 43 - 7 4z = 36 z = 9
What is 4z -z plus z plus 1 plus 1 plus 2z?
To simplify the expression (4z - z + z + 1 + 1 + 2z), first combine the like terms. The (z) terms are (4z - z + z + 2z), which simplifies to (6z). The constant terms are (1 + 1), which equals (2). Therefore, the simplified expression is (6z + 2).
X plus y-z equals 2 -x-5y plus 2z equals 21 5x plus 4y-4z equals 12?
I used the matrix method to find the answer: x=4, y=-7, z=-5.
10x plus 2y plus 8z-5x plus 4z-4y equals?
10x + 2y + 8z - 5x + 4z - 4y = 10x - 5x + 2y - 4y + 8z + 4z = (10 - 5)x + (2 - 4)y + (8 + 4)z = 5x - 2y + 12z
What is 4z - 11 equals 45?
4z-11=45 4z=56 z=14
What is 6z plus 4-4z equals 6 plus z-7 simplified?
6z-4z-z = 6-7-4 z = -5
19 - 4z equals -5 z equals?
Add 4z to each side: 19 = -z so z = -19
What is 7 plus 4z equals 43?
7 + 4z = 437 + 4z -7 = 43 - 7 4z = 43 - 7 4z = 36 z = 9
Z squared equals 4z plus 21?
(z=-3) and (z=7)
What is 4z -z plus z plus 1 plus 1 plus 2z?
To simplify the expression (4z - z + z + 1 + 1 + 2z), first combine the like terms. The (z) terms are (4z - z + z + 2z), which simplifies to (6z). The constant terms are (1 + 1), which equals (2). Therefore, the simplified expression is (6z + 2).
What is x plus 4z-5-3x then x equals 2 and z equals 3x?
If the question is x + 4z - 5 - 3x when x = 2 and z = 3x, then First simplify the original statement x + 4z - 5 - 3x = 4z - 5 - 2x Secondly substitute in 3x for z 4z - 5 - 2x = 4*3x - 5 - 2x = 12x - 5 - 2x = 10x - 5 Lastly substitute 2 for the x 10x - 5 = 10*2 - 5 = 20 - 5 = 15 or x + 4z - 5 - 3x when x = 2 and z = 3x, so z = 3*2 = 6 x + 4z - 5 - 3x = 4z - 5 - 2x (replace the variables with the corresponding values) = 4*6 - 5 - 2*2 = 24 - 5 - 4 = 24 - 9 = 15
3y plus 4z plus 12y equals 3y?
3y + 4z + 12y = 3y -3y -3y ------------------------- 4z + 12y = 0 divide everything by 4 z + 3y = 0 -3y -3y z = -3y
X plus y-z equals 2 -x-5y plus 2z equals 21 5x plus 4y-4z equals 12?
I used the matrix method to find the answer: x=4, y=-7, z=-5.
4z plus 6 divided by 3 equals?
That depends entirely on what the value of z is.
10x plus 2y plus 8z-5x plus 4z-4y equals?
10x + 2y + 8z - 5x + 4z - 4y = 10x - 5x + 2y - 4y + 8z + 4z = (10 - 5)x + (2 - 4)y + (8 + 4)z = 5x - 2y + 12z
What is 4z - 11 equals 45?
4z-11=45 4z=56 z=14
5x-2y plus 3z-2x-y-4z equals?
5x-2y+3z-2x-y-4z=3x-3y-z
