Answer:
A variable is a letter, for example x, y or z, that represents an unspecified number.
6+x=12
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.
Step-by-step explanation:
6z+4x=?
Solution: Replace x with 3 and z with 2 to evaluate the expression.
6z+4x=?
6⋅2+4⋅3=?
12+12=24

Answer: Did you mean to rewrite that
Step-by-step explanation:
Ummm What? soooo what are you looking for? if N is 8 that means C is larger than four. if you want an equation then here you go.
C > N/2
Answer:
To get to -3 you can do 1+-4
