3x + y = 1 y + 4 = 5x what is the resulting equation?

The value of x and y for the given expression is

( x , y ) = (   , )

Step-by-step explanation:

Given algebraic expression as :

3 x + y = 2      .....A  and

y + 4 = 5 x

Or, y = 5 x - 4         .........B

Now, Solving both equation to get x and y value

So, 3 x + y = 2  

or,  3 x + ( 5 x - 4 ) = 2

Or, 3 x + 5 x - 4 = 2

or, 8 x = 2 + 4

Or, 8 x = 6

∴  x =

or, x =

Now, Put the value of x in eq B

y = 5 x - 4

Or, y = 5 ×   - 4

or, y =  

∴   y =

Hence The value of x and y for the given expression is

( x , y ) = (   , ) Answer

the answer is b.)
