It is an expression and a term that are of equal value
5x=4012y=84124
Given a value of x, find the value for -3x + 2
7h - 2 - 51 is an expression NOT an equation. An expression cannot be solved for the value of a variable.
-4 (-9 +5 = -4)

20
5x=4012y=84124
Given a value of x, find the value for -3x + 2
That will depend on the plus or minus value of 12 which has not been given.
7h - 2 - 51 is an expression NOT an equation. An expression cannot be solved for the value of a variable.
-4 (-9 +5 = -4)
2 squared is 4 3 cubed is 27 27 plus 4 is 31
That depends on the value of x in the given expression
-13 Plug 5 in and multiply it by -5 which equals -25 12 - 25 = -13
Expression. Equations have equals signs.
Oops! That's not an equation. It has no 'equals' sign ( ' = ' ) in it, so it's just an 'expression' that stands for a number. The number that it stands for depends on the value of 'x', and any time 'x' changes, the value of the expression changes.
