# Each Equation is Followed by the Values of the Variable. Decide Whether These Values Are the Solutions of that Equation. - SSC (English Medium) Class 8 - Mathematics

ConceptSolution of Equations in One Variable

#### Question

The Equation given below is followed by the values of the variable. Decide whether these values are the solutions of that equation.

2a + 4 = 0, a = 2, −2, 1

#### Solution

2a + 4 = 0, a = 2, −2, 1

2a + 4 = 0

⇒ 2a + 4 - 4 = -4

⇒ 2a = -4

Dividing both sides by 2

⇒ (2"a")/2 = -4/2

⇒ a = -2

Hence, a = −2 is the solution of the equation.

Is there an error in this question or solution?
