60j + 2z = 6
I used the matrix method to find the answer: x=4, y=-7, z=-5.
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
13y+3z+8
-2z + 3
2z+9.75-7z=-5.15
(-3) x (-2z - 7) = 6z + 21 = 3 (2z + 7)
60j + 2z = 6
I used the matrix method to find the answer: x=4, y=-7, z=-5.
The answer to 2Z plus 9.75 subtract 7Z subtract equals 14.90. This is a math problem.
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
13y+3z+8
z = 18.5 6z - 24 = 2z + 50 Take the -24 to the other side of the equals and change its sign; take the 2z to the other side of the equals and change its sign: => 6z - 2z = 50 + 24 => 4z = 74 Divide both sides by 4: => z = 18.5
-2z + 3
By including its plus or minus signs
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
x=3 y=2 z=6
