Chapter 2
Lesson 3 (Write 2-step equations)
➗
the quotient, divided by, ratio
✖️
of, times, multiplied by, the product of
-
the difference, decreased by, minus, less, less than, subtracted from
=
equals, is
+
the sum, increased by, plus, more than, added to
Lesson 5 (Solve multi-step equations)
One solution, 2x=50, x=25
Identity (Many solutions), 4x+2 = 4x+2, 2=2
No solution, 3x + 4= 3x, 4=0
Lesson 1 (Inverse property of multiplication)
a/b . b/a = 1, whereas a & b ≠ 0
Lesson 4 (Solve equations with variables on each side)
7 + 5m = 6m, is 7= 6m - 5m, so m= 7
Lesson 2 (Solve 2-step equations)
2x + 9 = 21, becomes 2x = 21-9, 2x = 12, so x = 6
