What’s the difference???
Help please

Answer: D
Step-by-step explanation:
An equation would look like this:
x+1=3
An expression would look like this:
x+1
As you can see, an expression has no equal sign. Conversely, an equation does. That is the primary difference between a(n) (algebraic) expression and equation.
The Answer is D because an algebraic equation would look like y+4=15
and an algebraic expression would be y+4
