Question

7m+4n=3m+2n then m/n=?
​

Answer 1

Answer:

-1/2

Step-by-step explanation:

7m-3m = 2n-4n

4m= -2n

m/n = -2/4 = -1/2

I hope this is going to be helpful for..

Answer 2

Given :

• 7m + 4n = 3m + 2n

To find :

The value of

$\boxed{ \sf \frac{m}{n} }$

Evaluate :

Here it is given that

$\: \: \: \: \: \: \: \: \: \: \: \rightarrow \sf7m+4n=3m+2n$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \rightarrow \sf7m - 3m = 2n - 4n$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \rightarrow \sf4m = - 2n$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: { \boxed {\boxed{ \sf \: mn = \frac{ - 2}{4} }}}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: { \boxed{ \boxed{ \sf \: mn= \frac{ - 1}{4}}}}$

More Information :

• To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number.

what is Algebraic expression :

• An algebraic expression is an expression built up from integer constants, variables, and the algebraic operations.
