bearing in mind that
standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
8 - 5y = - 2x
2x - 5y = - 8

x + 12 = 4x - 6
+ 6
x + 18 = 4x
- x
18 = 3x
/3
x = 6
