In Exercises 1 to 6, simplify by combining similar terms. ( 3 x + 2 ) + ( 2 x − 3 ) − ( x + 1 )

To determine

To simplify:

(3x+2)+(2x3)(x+1)

Explanation

Forms of the Distributive Axiom:

The Distributive Axiom distributes multiplication over addition:

a(b+c)=ab+acab+ac=a(b+c)

The Distributive Axiom distributes multiplication over subtraction:

a(bc)=abacabac=a(bc)

Calculation:

Given:(3x+2)+(2x3)(x+1)

Now we have to simplify by combining similar terms.

Remove parentheses: (a)=aBy expanding the last bracket, we have to multiply its content by (-1)This gives us:
