1st answer: x= -7/2 -5/4y + 1/2z
2nd answer: x= 6 + 1/7y -2/7z
3rd answer: x= 28/3 -1/3y -4/3z
Steps
4x + 5y -2z = -14
Move variables to the right
4x = -14 -5y +2z
Divide both sides by 4
X= -7/2 -5/4y +1/2z
Answer
X= -7/2 -5/4y +1/2z
7x -y +2z =42
Move variables to the right
7x = 42 +y -2z
Divide both sides by 7
X= 6 + 1/7y -2/7z
Answer
X= 6 + 1/7y -2/7z
3x +y +4z = 28
Move variables to the right
3x =28 -y -4z
Divide both sides by 3
X= 28/3 -1/3y -4/3z
Answer
X= 28/3 -1/3y -4/3z
If a package is dropped at a height of 121m ,above the Earth, from a window. It will take <span> 5.53 seconds for the package to reach the ground. </span>
3x+10=310
3x+10-10=310-10
3x=300
3x/3=300/3
x=100
Therefore x is equal to one hundred
