Problem Solve −4+4−6=12 − 4 j + 4 − 6 = 12 . Solution First we need to isolate the variable term by eliminating the denominator of the fraction. Multiply both sides by −6 − 6 . ( ( )−4+4−6=12( ) − 4 j + 4 − 6 = 12 ( ) ) −4+4= − 4 j + 4 = Next, subtract 4 4 from both sides. −4= − 4 j = Divide both sides by −4 − 4 . = j =
