Question

2. Solve the following equations:

(d) - 4(2 + x) = 8
​

Answer 1

Answer:

x = -- 4

Step-by-step explanation:

--4 (2+x) = 8

= (-- 8) + ( --4x) = 8

(--4x) = 8+8

--4x = 16

x = 16/--4

x = --4 .

Answer 2

Given equation:

-4 (2+x) = 8

__________________

Solution:

-4 (2+x) = 8

-8 -4x = 8

-8 -8 = 4x

-16 = 4x

$\dfrac{ - 16}{4} = x$

$\boxed {\boxed {\sf {\pink {-4 = x}}}}$

__________________

Verification:

On substituting the value of x as (-4) in the equation,

-4 (2+x) = 8

-4 {2+(-4)} = 8

-4 {2-4} = 8

-4×(-2) = 8

8 = 8

LHS = RHS

Hence Verified!
