Owen solves the equation below and his steps are shown. When he plugged his solution back into the original equation, he did not get a true statement. Please help him identify THE FIRST STEP in which he made an error.
ORIGINAL EQUATION: 3 (x-4) = -4 - 2 (x-5)
STEP 1: 3x - 12 = -4 - 2x +10
STEP 2: 3x -12 = -2x - 4 +10
STEP 3: 3x - 12 = -2x + 6
STEP 4: subtract -2x from either side
STEP 5: x - 12 = 6
STEP 6: add 12 to either side
STEP 7: x=18
