Question

. Verify by substitution that (c) the root of 5x - 8 = 2x - 2 is x = 2
​

Answer 1

Answer:

The Correct Answer is x = 2

Step-by-step explanation:

Since it is asked to verify weather x = 2 is a root or not,

We will directly put x = 2 in the given equation,

5 (2) - 8 = 2 (2) - 2

10 - 8 = 4 - 2

2 = 2

Hence LHS = RHS, therefore the equation is balanced and it is confirmed that x = 2 is the root

Answer 2

Step-by-step explanation:

5x−8=2x−2,x=2

LHS=5(2)−8=2

RHS=2(2)−2=2

LHS=RHS

∴x=2 is a root
