129

Step-by-step explanation:

The order of operations is PEMDAS

P = parenthesis

E = exponents

M = multiplication

D = division

A = addition

s = subtraction

starting with

+ 9 (12 / 3 x 2) - 7

We first work the terms in the parenthesis ( 12 / 3 x 2)

A rule is if all the operations are multiplication and division only we work from left to right so (4 x 2) then (8)

+ 9(8) - 7

Next we take care of the exponent (the remaining parenthesis are a multiplication operation not parenthesis that contain other operations)

64 + 9(8) - 7

Next we do the multiplication

64 + 72 - 7

Another rule is if all the operations are addition and subtraction we work from left to right

136 - 7 = ?

? = 129

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.
