First step is breaking down the word problem. I think of a number. U don’t know the number so called it x The number add 3. X + 3 Then it says multiply the outcome by 7 You are not sure what what the outcome could be so you put it in brackets (X+3) times it by 7 (X+3) 7 The solution is 24.5 Solution means equal (X+3) 7 = 24.5 Now you have the equation To solve for x By the BOMDAS method You times 7 by what is inside the brackets 7x + 21 = 24.5 Now transpose 7x = 24.5 - 21 7x = 3.5 Divide both sides by 7 7x/7 = 3.5/7 Which cancel out 7 and leave x So the original number is Or u could say x = 0.5
