Question

Solve the equation: 9x − 2 = 4(x + 3)

Answer 1

5x=14
x=14/5

Answer 2

Distribute on the right hand side.

\(\Large \color{Black}{\Rightarrow 9x - 2 = 4x + 12 }\)

Add 2 to both sides.

\(\Large \color{Black}{\Rightarrow 9x = 4x + 14 }\)

Subtract 4x from both sides.

\(\Large \color{Black}{\Rightarrow 5x = 14}\)

Divide both sides by 5.

\(\Large \color{Black}{\Rightarrow x = 14/5 = 2.8 }\)
