Step-by-step explanation:
Simplifying
x + -2y + 3z = 16
Solving
x + -2y + 3z = 16
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2y' to each side of the equation.
x + -2y + 2y + 3z = 16 + 2y
Combine like terms: -2y + 2y = 0
x + 0 + 3z = 16 + 2y
x + 3z = 16 + 2y
Add '-3z' to each side of the equation.
x + 3z + -3z = 16 + 2y + -3z
Combine like terms: 3z + -3z = 0
x + 0 = 16 + 2y + -3z
x = 16 + 2y + -3z
Simplifying
x = 16 + 2y + -3z
