Question

2x + 37 = 7x + 42x = ???

Answer 1

Solve;

`\begin{gathered} 2x+37=7x+42 \\ \text{Collect all like terms and you'll have,} \\ 2x-7x=42-37 \\ \text{Note that a positive number becomes negative once it crosses the equality sign} \\ \text{And vice versa for a negative number} \\ 2x-7x=42-37 \\ -5x=5 \\ \text{Divide both sides by -5} \\ (-5x)/(-5)=(5)/(-5) \\ x=-1 \end{gathered}`

Therefore, x = -1
