Question 1(c) Give first the step you will use to separate the variable and then solve the equation: X - 1 = 5
x-1=5 ⇒ x-1+1=5+1 [Adding 1 both sides] ⇒ x = 6
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(d) Give first the step you will use to separate the variable and then solve the equation: 4x=25
Question 2(f) Give first the step you will use to separate the variable and then solve the equation: z3=54
Question 2(g) Give first the step you will use to separate the variable and then solve the equation: a5=715
