29

Answer 1

Let me try

Answer 2

\( \color{Black}{\Rightarrow 8x - 4 - 3 = 9x - 36 }\)

\( \color{Black}{\Rightarrow 8x - 7 = 9x - 36 }\)

\( \color{Black}{\Rightarrow 8x = 9x - 29 }\)

\( \color{Black}{\Rightarrow -x = -29 }\)

Answer 3

Oopsie....you got a sign wrong

Answer 4

\( \color{Black}{\Rightarrow -a = -b \Longleftrightarrow a = b }\)
