  Lesson 7: Two-step equations with decimals and fractions
  
  # Two-step equations with decimals and fractions
  
  Let's practice some two step equations, some of which require merging terms and using the distributive property. Created by Sal Khan and CK-12 Foundation.

  • Math needs to solve its own problems. I'm not a therapist.
  • words of a true man
  • At , Sal kept 0.6 as a decimal. Could you also make that into a fraction (6/10) and then multiply both sides by 10 (getting 6x = 120), then dividing both sides by 6, getting x = 20? It seems much easier that way.
  • Gauri, the way you described is a completely correct way of doing it, and I agree: it is easier. Usually, if you can covert decimals to fractions because fractions are easier to work with, that's a good way to do it.
  Hope that helps!
  • Dear math,
  She is gone.
  • math aint mathing today yall
  • At , why is it necessary to do the division? Couldn't you just do "Well, I know 6 goes into 12 2 times, but this is a 0.6, which is 10 times less that 6, so just multiply that quotient by ten and boom: 20 is the answer."?
  • Because even if this certain division problem was easy, he was demonstrating it so that you could understand and do harder ones more easily… I know- this reply is coming a little to far in the future. Outdated but- hope I helped.
  • Why do us students have to learn all subjects, but teachers can't teach all subjects?
  • They specialize in one topic. Thats why each teacher is so good at one subject cause they excelled in that area and are able to teach us well.
  • Why did he change 3s/8 to (3/8)S?
  • Thank You for these tips for two step equations. Is there other ways to do this?
  • In two steps equations one need to solve one part of the equation first to solve the whole equation . This is going to be a good way to do one way equation.
  • What is 13=-4x+9
  • I will demonstrate the steps towards solving the equation:
  ``Original equation:13 = -4x + 9Algebraic manipulations:13 - 9 = -4xx = (13 - 9) / -4x = -1Verification:13 = -4(-1) + 9, passesAnswer:.________.| x = -1 |.________.``
  
  • math be to complicated
