If 3x, 5y and 7z are equal terms, them each of them will equal one third of 357, or 119.
3x = 119
x = 39 and 2/3
5y = 119
y = 23 and 4/5
7z = 119
z = 17
Such an equation has an infinite set of solutions. You can solve the equation for one variable, in terms of the other. Then, by replacing different values for one of the variables, you can get different solutions.
Without an equality sign and not knowing the plus or minus values of the given terms it can't be considered to be an equation.
Unlike terms.
They are called like terms

A method for solving a system of linear equations; like terms in equations are added or subtracted together to eliminate all variables except one; The values of that variable is then used to find the values of other variables in the system. :)
A single equation with two variables can be solved for one of the variables, in terms of the other. For example, a rectangle's area is A = wh (width x height). Now let's assume you know the area: 20 = wh. You can solve for any of these variables in terms of the other, for example, w = 20/h. That is, once you assign a value to "h", you can calculate "w". But you don't know the specific values for "w" and "h", because the equation has an infinite number of solutions.If you want to know specific values for the variables, in general, you need two different equations with 2 variables - or 3 equations with 3 variables, etc.

You can't. You can only subtract like terms. Like terms must have exactly the same variables and exponents on the variables.
terms whose variables are the same.
