Answer 2

Answer:

$\large\boxed{\boxed{\underline{\underline{\maltese{\blue{\pmb{\sf{\: Solution :- \: \: \: x = 7 }}}}}}}}$

Step-by-step explanation:

The given equation is 8 + 4 = 2 (x - 1). We need to find the value of x.

Let's solve it.

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

Add 8 & 4 in the left side of the equation.

$\pmb{8 + 4 = 2(x - 1)}\\\pmb{12 = 2(x - 1)}$

Now, multiply 2 by x & 1 to remove the brackets.

$\pmb{12 = 2(x - 1)}\\\pmb{12 = 2x - 2}$

Now, bring 2 to the left side of the equation as it's a constant. 2 will be added to 12.

$\pmb{12 = 2x - 2}\\\pmb{12 + 2 = 2x}\\\pmb{14 = 2x}$

Divide 114 by 2.

$\pmb{14 = 2x}\\\pmb{\frac{14}{2} = x }\\\large{\boxed{\pmb{7 = x}}}$

•°• The value of x is 7.
