What is 6x plus 13 equals 2x plus 7?

Answer 1

You want to move all like numbers and variables to the same side. You have 6x+13=2x+7. Subtract 2x from each side to have 6x-2x+13=7. Now subtract 13 from each side to have 6x-2x=7-13. Now work out each side to have 4x= -6. Divide each side by 4 to get x alone. Your answer should be x= -6/4. Reduce to -3/2. If you cannot have improper fractions, the mixed number would be -1 and 1/2. If you must answer in decimals, remember that 1/2=0.5, so your answer is -1.5.
