How do I evaluate an expression?
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
How do you evaluate an expression in 7th grade?

How do I solve this equation?
In order to solve this equation we need to isolate the x variable. So the first thing we need to move is the 5.. We want to get x by itself on the left side so we need to get rid of the 5..
How do I simplify an expression?
Because they carry the same variable x. So we can combine 5x. And negative 2x 5 plus negative 2 is the same as 5 minus 2 and that’s 3x. Now 8 and 5 are constants they’re like terms.
