A/a-x =b/b+x make x the subject of the formula
To make x the subject of the formula, we need to isolate it on one side of the equation.
Start by cross-multiplying:
A(b + x) = B(a - x)
Expand both sides:
Ab + Ax = Ba - Bx
Now, let's gather the terms involving x on one side:
Ax + Bx = Ba - Ab
Factor out x:
x(A + B) = Ba - Ab
Finally, divide both sides by (A + B) to solve for x:
x = (Ba - Ab) / (A + B)
Thus, x is the subject of the formula.
