Question

what to do in this expression ? full explanation please.
2 (3m-1) = m+10 ??????

Answer 1

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

              Given data:- $2(3m-1)=m+10.$

              To find:- Value of the expression.

              Solution:-

• Here we will use the transposition method.

• Transposition is one of the linear equations.

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

• Then we Simplify the equation in LHS and RHS.

• Now Simplify the equation using arithmetic operations.

        By using the transposition method.

        we get,

                  $2(3m-1)=m+10\\=>6 m-2=m+10\\=>6 m=m+12\\=>5m=12\\=>m=\frac{12}{5} .$

    Hence we will get the value $m=\frac{12}{5} .$

Answer 2

Answer:

m = 12/5 or 2.4

Step-by-step explanation:

→ This is an equation which means both sides of the '=' sign are equal as given in the question. What we have to do is simplify this expression in such a way, that we get a numerical value for 'm'.

→ 1 thing worth noting is that in equations, as long as your calculations are correct, the answer may be a fraction, or a decimal, or a rational number, etc.

SO,

2(3m-1) = m+10

⇒ 6m - 2 = m+10 {Using distributive property, and thus we multiply each term in the expression by 2}

⇒ 6m-m=10+2 {Transposing m from RHS to LHS and -2 from LHS to RHS}

⇒ 5m = 12 {Subtracting -m from 6m and adding 2 to 10}

⇒  m = 12/5 {Finally, dividing 12 by 5 to get our answer}

Therefore, the value of m is 12/5 or you can divide 12/5 to get 2.4 as your answer which is also correct.
