Question

Find the value of x for the given equation 12 + 2x + 18 = 10​

Answer 1

Step-by-step explanation:

Step-by-step explanation:

$12 + 2x + 18 = 10 \:$

• $\longrightarrow \: 2x + 30 = 10$
• $\longrightarrow \: 2x = - 30 + 10$
• $\longrightarrow \: 2x = - 20$
• $\longrightarrow \: {\bold x = \frac{ \cancel{ - 20}^{ - 10} }{2}}$
• $\longrightarrow \: \fcolorbox{red}{green}{x = - 10}$

Answer 2

Answer:

We will get the value of x=-10.

Step-by-step explanation:

• We have to evaluate the above expression by using the given data.

              Given data:-  12+2x+18=10.

              To find:- Value of x.

              Solution:-

• Here we will use the transposition method.

• Transposition is one of the linear equations.

• To solve the transposition method we will Identify the variables and constants.

• Then we Simplify the equation in LHS and RHS.

• Now Simplify the equation using arithmetic operations.

        $12+2x+18=10\\=>30+2x=10\\=>2x=10-30\\=>2x=-20\\=>x=\frac{-20}{2}\\=>x=-10$
