Give the steps you will use to separate the variables and then solve the equation : – 5 + 3x = 16 |
|
Answer» Given – 5 + 3x = 16 ⇒ – 5 + 3x + 5 = 16 + 5 (Add 5 on both sides) ⇒ 3x = 21 ⇒ 3x/3 = 21/3 (Divide by 3 on both sides) ⇒ x = 7 Check: Substitute x = 7 in the given equation LHS = – 5 + 3x = – 5 + 3(7) = – 5 + 21 = 16 = RHS Hence verified. |
