Kelsey solved the following equation: 7x − one over two(8x + 2) = 6 step work justification 1 7x − 4x − 1 = 6 2 3x − 1 = 6 3 3x = 7 4 x = 7 over 3 which of the following has all of the correct justifications kelsey used to solve this equation?

the given equation is

⇒7x-(8x+2)=6

1.⇒7x-4x-1=6[using distributive property a×(b+c)=a×b+a×c]

2.⇒3x-1=6 [subtracting variable having lower coefficient from variable of higher coefficient ]

3.⇒3x=6+1 [bringing constant term on one side of equation]

4.⇒3x=7

5.⇒x=

i have written the steps as well as their justification why jesley has done this. jesley forgot to write a step which is 3rd step otherwise all steps are correct.
