Simplify (b - 7) + (3b - 9)

2b+ 9

Step-by-step explanation:

(7−b)+(3b+2)

We can solve this pretty quickly using the order of operations:

P: Parentheses

E: Exponents

M: Multiplication

D: Division

A: Addition

S: Subtraction

P: Parentheses. There is nothing to simplify inside the parentheses, so we can get rid of them

=7−b+3b+2

There are no exponents, multiplication, or division so we can skip those.

Addition/Subtraction will occur if we simply add or subtract like terms. First, it may be helpful to combine like terms so that they are next to each other:

=7+2+3b−b

=9+2b or  2b+9

the first question mark is 6 and the second question mark is 26 (the square root)
