substitute the values of the variable inside the algebraic expression.
for example:
find the value of x when y = -4, z= 2, a=3, z= 0
0.5x + y -z (a+b)= 8
0.5x -az -bz +y = 8
0.5x -4=8
0.5x= 4
x= 4/0.5= 8

To find the value of an algebraic expression is to evaluate it.
to simplify!!* * * * *No. It is to EVALUATE.
evaluate. : )
That will depend entirely on the algebraic expression which has not been given.
For each of a list of algebraic expressions, find one or more common factors and factorise the expression.
