12 x = 2⇒2x = 4 Multiply both sides by 2⇒2x - 3 = 4 - 3 subtracting 3 from both sides⇒2x - 3 = 1 Again, x = 2⇒3x = 6 Multiply both sides by 3⇒3x + 3 = 6 + 3 adding 3 from both sides⇒3x + 3 = 9 Again, x = 2⇒4x = 8 Multiply both sides by 4⇒4x - 1 = 8 - 1 subtracting 1 from both sides⇒4x - 1 =7

(12) . x = 2 \Rightarrow 2 x = 4 (Multiply both sides by 2) \Rightarrow 2 x - 3 = 4 - 3 (subtracting 3 from both sides) \Rightarrow 2 x - 3 = 1 Again, x = 2 \Rightarrow 3 x = 6 (Multiply both sides by 3) \Rightarrow 3 x + 3 = 6 + 3 (adding 3 from both sides) \Rightarrow 3 x + 3 = 9 Again, x = 2 \Rightarrow 4 x = 8 (Multiply both sides by 4) \Rightarrow 4 x - 1 = 8 - 1 (subtracting 1 from both sides) \Rightarrow 4 x - 1 = 7
