One step equations Add Subtract Multiply Divide
When we solve an equation, our goal is to isolate our variable by using our inverse operations. What does isolate mean? What operation is the inverse of… Addition? Multiplication?
Addition X + 5 = -9 X + 5 - 5 = -9 -5 X = -14 6 + X = -4 6 - 6 + X = -4 - 6 X = 2
You try! 10 = X + 3 5 + X = 9 6 = 3 + X
Answers!!! X = 7 = 4 = 3
Equations with subtraction X - 5 = 8 X - 5 + 5 = 8+5 X = 13 -5 + X = 6 -5 + 5 + X = 6 + 5 X = 11
You try! X - 7 = -1 X - 4 = 66 8 = X - 2 -8 = X – 2
Answers!!! X = 6 = 70 X = 10 X = -6
Multiplication of Equations 3X = -9 3X/3 = -9/3 X = -3 -5X = -40 -5X/-5 = -40/-5 X = 8
You try! 4X = -16 -1X = 9 6 = 5X 12X = 3
Answers!!! X = -4 X = -9 X = 6/5 X = 1/4
Division of Equations 1/2X = 4 (2/1)1/2X = 4(2) X = 8 -3/4X = 6 (-4/3)(-3/4)X = 6(-4/3) X = -8
Answers!!! X = 27 X = -28 X = -3 X = 16
