Solving One Step Equations Kaitlyn Sand 5.03 Solving one-step equations
Order of Operations PEMDAS right to left to solve: 9−3×2+5 (multiplication) 9−6+5 (subtraction) 3+5 (addition) 8
Solving One Step Equations Opposite of PEMDAS; SADMEP. S – subtraction A – addition D – division M – multiplication E – exponents (remember, we haven’t P – parenthesis talked about these yet!)
One Step Equations -Perform 1 step to solve -Try to get “X” by itself -Do the same operation to both sides -Just like what you did on excel math:
Excel Math + 3 = 5 Now, we use X as a place holder instead of the empty square. X + 3 = 5
What you do to ONE side, you MUST do to the other. X + 3 = 5 (Subtract 3 from both sides) -3 -3 X = 2
2X = 10 2 2 X = 5 6 – 1X = 2 -6 -6 -1X = -4 -1 -1 X = 4
Foamy Squishy Things Introduction = X + = 0 = 1 = -1
X + 3 = 5 You can also use foamy squishy things to solve problems. + = =
Using Foamy Squishy Things Set up your foamy squishy things in the form of this problem: X + ˉ5 = 2
