Solve
[tex]1 + 4x =  - 5 + 7x[/tex]
First, place the unknown x on the left.
[tex]4x - 7x =  - 5  - 1[/tex]
Then, solve for x.[tex]4x - 7x =  - 5 - 1 \\  \:  \:  \:  \:  \:  \:  \:  - 3x =  - 6 \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  x =  \frac{ - 6}{ - 3}  \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  x = 2[/tex]
