Question

ii) 2+2(x+2=8,solve​

Answer 1

Solution:

2 + 2x + 2 = 8

⇒ 2 + 2 + 2x = 8

⇒ 4 + 2x = 8

⇒ 2x = 8 - 4 = 4

⇒ x = 4/2

⇒ x = 2

Answer: x = 2 is the root of the above equation.

Check:

On substituting x with 2 in the LHS of above equation, we get,

2 + 2(2) + 2 = 2 + 4 + 2 = 6 + 2 = 8 = RHS

Answer 2

Answer:

x=1

Step-by-step explanation:

$2 + 2(x + 2) = 8 \\ 2 + 2x + 4 = 8 \\ 2x + 6 = 8 \\ 2x = 8 - 6 \\ x = \frac{2}{2} \\ x = 1$
