Question 1(d) Give first the step you will use to separate the variable and then solve the equation: X + 6 = 2
x+6=2 ⇒ x +6-6=2-6 [Subtracting 6 both sides] ⇒ x = -4
Question 1(b) Give first the step you will use to separate the variable and then solve the equation: x + 1 = 0
Question 1(a) Give first the step you will use to separate the variable and then solve the equation: x - 1 = 0
Question 2(b) Give first the step you will use to separate the variable and then solve the equation: b2=6
Question 2(d) Give first the step you will use to separate the variable and then solve the equation: 4x=25
Question 2(h) Give first the step you will use to separate the variable and then solve the equation: 20t = -10
