Why the error?🤔

Question

This program finds the value of x in the equation
of format: x operator a = b
where:
1 - "x" can be any algebraic variable "a-z"
2 - "operator" can be ×,÷,+ or -
3 - "a" is the second operand and "b" is the result of the calculation

e.g x × 3 = 15, b - 30 = 56, z ÷ 4 = 12
