Question 3(c) Give first the step you will use to separate the variable and then solve the equation: 20p3=40
20p3=40 Step I : 20p3×3=40×3⇒20p=120 [Multiplying both sides by 3] Step II : 20p20=12020⇒p=6 [Dividing both sides by 20]
Question 3(a) Give first the step you will use to separate the variable and then solve the equation: 3n - 2 = 46
Question 2(d) Give first the step you will use to separate the variable and then solve the equation: 4x=25
Question 1(a) Give first the step you will use to separate the variable and then solve the equation: x - 1 = 0
Question 1(b) Give first the step you will use to separate the variable and then solve the equation: x + 1 = 0
Question 1(d) Give first the step you will use to separate the variable and then solve the equation: X + 6 = 2
