Solve for x A=x+y+z

$A = x + y + z$

Step 1

Rewrite the equation as $x + y + z = A$ .

$x + y + z = A$

Step 2

Move all terms not containing $x$ to the right side of the equation.

Subtract $y$ from both sides of the equation.

$x + z = A - y$

Subtract $z$ from both sides of the equation.

$x = A - y - z$
