Question

I need to remember how to solve this problem

Answer 1

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