Yes, you can add or subtract a number with a variable and a number without one, but they cannot be combined into a single term. For example, you can simplify the expression (3x + 5) to show that it consists of a variable term (3x) and a constant term (5), but they remain separate. The result is (3x + 5), not a single term.

When multiplying a variable with an exponent with a variable that doesn't have an exponent do you add the exponent or subtract it multiply it?

When multiplying a variable with an exponent by a variable without an exponent, you add the exponent of the first variable to the exponent of the second variable (which is considered to be 1). For example, if you multiply (x^2) by (x), the result is (x^{2+1} = x^3). This rule applies to variables with the same base.

When solving a system by multiplying and then adding or subtracting how do you decide whether to add or subtract?

When solving a system of equations by multiplying and then adding or subtracting, you decide whether to add or subtract based on the coefficients of the variables you want to eliminate. If the coefficients of one variable are opposites (e.g., +3 and -3), you would add the equations to eliminate that variable. Conversely, if the coefficients are the same (e.g., +3 and +3), you would subtract one equation from the other to eliminate the variable. The goal is to simplify the system and isolate one variable for easier solving.
