Verbal Expressions • A number multiplied by 9 and increased by 10 • The difference between 6 times a number and 12. • Two more than 7 times a number • 3 less than 4 times a number
Multi-Step Equations • Solve using inverse operations • x/5 – 6 = 10 • 4(x - 5) = 12
Multi-Step Equations • Solve using inverse operations • -13 + z/4 + 7 = -9 • -6x + 2 – 4x + 10 = 32
Variables on Both Sides of the Equation USE C.C.M.S.
15 – x =2(x + 3) • USE C.C.M.S
2b + 4(b - 5) – 2 = 92 • USE C.C.M.S.
1.2y + 2.8y + 5 = 5y - 9 • USE C.C.M.S.
Absolute Value • Note number of solutions and the solutions • | x + 7| = 18 • |9 + x| = 0 • |4x| = -12 • |x - 4| = 9 • |5x + 10| - 3 = -3 • |3x – 2| = -9
