Question

3x=7x-5 find the value of x and check
​

Answer 1

Step-by-step explanation:

3x=7x-5

3x-7x=-5

-4x=-5

x= 5/4

check

3(5/4)=7(5/4)-5

15/4= 35/4-5

15/4= 35/4-20/4

15/4= 15/4

LHS =RHS

Answer 2

Answer:

=> The value of x is $\frac{5}{4}$ and it satisfies the expression.

Step-by-step explanation:

Given that:-

$3x=7x-5$

To find:- The value of the expression, and also verify that it satisfies the given expression or not.

To solve this expression, we have to use the transposition method:  

As we have,

=> $3x=7x-5$

Now subtract both sides by $7x$, we get

=> $3x-7x=7x-5-7x$

Simplifying it further, we get

=> $-4x = -5$

Divide both sides by $-4$,

=> $x = \frac{5}{4}$

Hence, the required solution is $\frac{5}{4} .$

Verification:-

Plug the value of $x = \frac{5}{4}$ in the given expression,

=> $3(\frac{5}{4}) =7(\frac{5}{4})-5$

Simplifying it further, we get

=> $(\frac{15}{4}) =(\frac{35}{4})-5$

=> $(\frac{15}{4}) =(\frac{35}{4})-(\frac{20}{4})$

=> $(\frac{15}{4}) =(\frac{15}{4})$

LHS = RHS
