we want to isolate x on one side by performing simple operations to both sides
17x - 42 = -39
add 42 to both sides
17x - 42 + 42 = -39 + 42
17x = +3
divide both sides by 17
x =
x =

:
To check this in the original equation
17x - 42 = -39
replace x with 3/17
17 - 42 = -39
17's cancel, leaving
3 - 42 = -39
-39 = -39; equality, confirm our solution of x = 3/17
