How many terms are in the expression when simplified

There are four (4) different terms

Step-by-step explanation:

Given;

2x + 3xy - (x + y) + 2

The terms are simplified as follows;

=2x + 3xy - (x + y) + 2

= 2x + 3xy - x - y + 2

collect like terms;

= 2x - x  - y + 3xy + 2

= x - y + 3xy  + 2

Thus, there are four (4) different terms in the simplified expression.

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

y=mx+b

step-by-step explanation:

m slope

b y-intercept
