Is it possible to solve an equation with different operations in it correctly without using orders of operation? I was having a discussion with my friend who believes you can solve an equation from left to right no matter what the operations are. I told my friend that the answer you get would not be correct, but they still insist they are right. Who is right and why?

solving Multi operation equations correctly

You want to evaluate an expression.
You have to specify the order of evaluating if you concatenate several multiary operations (e.g. a o b o c). "Multiplication and division before addition and subtraction" is the law for the basic arithmetic operations.
The value of your expression is 50 therefore.
Other orders of operations can be specified in the expression by brackets.
If you don't want to use brackets, you can apply Reverse Polish notation or Polish notation.
