[2.03] Solve: 4(2x − 1) − 3 = 9(x − 4) −29 <--- ? 32 13 29
\( \color{Black}{\Rightarrow 8x - 4 - 3 = 9x - 36 }\) \( \color{Black}{\Rightarrow 8x - 7 = 9x - 36 }\) \( \color{Black}{\Rightarrow 8x = 9x - 29 }\) \( \color{Black}{\Rightarrow -x = -29 }\)
Oopsie....you got a sign wrong
\( \color{Black}{\Rightarrow -a = -b \Longleftrightarrow a = b }\)
\( \color{Black}{\Rightarrow -x = -29 \Longrightarrow x = 29 }\)
