Jade solved the following equation: 3 + 5x – 7 = 3x – 9 step work justification 1 5x + 3 – 7 = 3x – 9 commutative property of addition 2 5x – 4 = 3x – 9 addition property of equality 3 2x – 4 = –9 subtraction property of equality 4 2x = –5 addition property of equality 5 x = –2.5 division property of equality which step has an incorrect justification?

Step 2

Step-by-step explanation:

From the original equation to step 1, 5x and 3 have been switched.  This is the commutative property of addition.

From step 1 to step 2, 3 and -7 have been combined to make -4.  This is not the addition property of equality; this is addition or simplification.

its step 4

Step-by-step explanation:

x = - 17

Step-by-step explanation:

−12x−60=144

add 60 to both sides

-12x-60+60=144+60

simplify

-12x=204

divide both sides by -12

-12/-12 = 204/-12

simplify and ur Answer!! is x=-17
