Distribute: -3x -12+4x. You multiply the -3 by the inside number -3•x =-3x, -3•4=-12 leave the 4x alone because it is not in the parentheses. Now put all the common factors together such as -3x and 4x would equal X because “if the signs are different subtract and keep the larger” 4 is the highest and it is positive so subtract 3 from 4 which is 1x you can say X. -12 would Stay the same so the answer is X-12
