Question 2(h) Give first the step you will use to separate the variable and then solve the equation: 20t = -10
20t = -10 ⇒20t20=−1020 [Dividing both sides by 20] ⇒t=−12
Question 2(d) Give first the step you will use to separate the variable and then solve the equation: 4x=25
Question 3(a) Give first the step you will use to separate the variable and then solve the equation: 3n - 2 = 46
Question 3(d) Give first the step you will use to separate the variable and then solve the equation: 3p10=6
Question 2(a) Give first the step you will use to separate the variable and then solve the equation: 3l= 42
Question 3(b) Give first the step you will use to separate the variable and then solve the equation: 5m + 7 = 17
