Question

2. Solve the
following equations
(a) 2(x + 4)=12
​

Answer 1

Answer:

x = 2

Step-by-step explanation:

$2(x + 4) = 12 \\ 2x + 8 = 12 \\ 2x = 12 - 8 \\ x = \frac{4}{2} \\ x = 2$

Answer 2

Answer:

x=2

Step-by-step explanation:

2(x+4)=12

This is a find x problem.

STEP 1: Multiply 2 with (x+4)

i.e., 2(x+4)= 2x+8

STEP 2: Take over 4 to another side(R.H.S)

I.e., 2x=12-8 (the sign of the integer changes once it is shifted to another side)

STEP 3: simplify RHS

I.e., 2x= 4

STEP 4: Shift 2 to RHS for further simplification.

x=4/2

x=2

Hope this helps
