First step would be to expand it and make it 2x + 14 + 3x = 12
Second step would be to add 2x + 14 + 3x so it can be 5x + 14
Third step would be to subtract 14 from both sides
Fourth step would be to subtract 12 - 14 so it can be -2
Last step to get your answer would be to divide both sides by 5
Answer to this whole equation: x = -2/5.
