You cannot solve an expression. You can only simplify it. Assuming you mean simplify, you do this by combining like terms. Since both terms have an "r" in them, you simply add the coefficients together. Example: 5x + 2x would be 7x Example: -3y + 8y would be 5y Example: -2p - 4p would be -6p You should be able to simplify your problem now.

When you have an expression you have to simplify by eliminating all grouping symbols and combining like terms.
3b-4-6b-5
It means to rewrite the expression so that it is in its simplest form. You can do this by combining like terms. For example: The equation 2x + 3x = 5 can be simplified to 5x = 5 by combining the "x's".
There are only the two terms, so 8xy
a + 7b + 2c
You add (or subtract) like terms. This will reduce the number of terms in the expression and that is the extent of simplification that you can achieve using this process.
If you have a expression that goes; 2x + 5x etc etc Simplifying the like terms is 7x 2x and 5x are like terms, but 2y and 2x are not. The variable needs to be the same.
The answer depends on the form of the radical expression.
Math can be difficult at times. To simplify a math expression, it is important to follow the order of operations, or PEMDAS.
What does it mean to simplify an algebraic expression?It means to take the problem to the lowest point you can take it to.
You have not told us what expression you wish to simplify.
The answer depends on what expression you do have and for what kind of shape!
