1
Solving Linear Equations with a variable on only one side of the equation

2
Basic Goal : Isolate the variable on one side using INVERSE operations. ◦ UNDO any Addition or Subtraction first to isolate the variable term. ◦ UNDO any Multiplication or Division second to isolate the variable. Solve: 1) 2x + 4 = -402) -18 = 4 – 3n

3
3) -2w + 4 = -84)15 = 7x + 1 5) 2.3x – 9.34 = 6.3 6) 15 = 6x – 3 + 3x

4
7) 3(x – 2) = 12 8) 3y – (y + 5) = 9 9) 5(3x + 1)- 12x = -2

5
Hint: clear fractions by multiplying each term by the LCD! 10) x + 2 = 3 3 5 11) 1 x + 4 = 7 2 8

6
12) 12 = 4d – 1 3 13) M – 6 = 2 5 14) 1 (x – 7) = -7 3
