Multi-Step Equations with Rational Numbers How are the problems below similar and different? ANSWER- Both will give you approximately the same answer once you perform your two steps to isolate the variable. But obviously one has fractions, the other decimals.

COMMON CORE #9B Solve Multi-Step Equations with Rational Numbers(decimals and fractions)

Multistep Equations with Decimals 0.88y – 5 = 8.2 Remember ADD first! 0.88y – 5 = y = 13.2 Then divide! 0.88y = y = 15 Check your answer 0.88(15) – 5 = – 5 = = 8.2

Multistep Equations with Decimals Check Your Answer -1.5(-1.6) = = p = 4.8 Subtract -1.5p = p = 2.4 Again, divide! -1.5p = p = -1.6

Your Two to Work and Check! -2.15k – 4.5 = ANSWERk = j + 12 = 47.2 ANSWERj = 4

Multistep Equations with 1 Fraction t = 24 You Work This! Answer d = -21

Multistep Equations with 2 Fractions Multiply thru by the LCM! You Work This! x =
