63 + 12x < 15 1st. We will subtract 63 on both sides, to leave 12x on one side by itself: 63 - (63) + 12x < 15 - (63) = 12x < -48
2nd: Then we divided by 12 on both sides to isolate x, or to leave x by itself. 12x /12 < -48 /12= x>-4
*Remeber, make sure to switch the signs from less than x to greater than x. We do that because we are either dividing or multiplying by a negative number!
