Answer:

The value of x and y for the given expression is

( x , y ) = (  [tex]\frac{3}{4}[/tex] , [tex]\frac{-1}{4}[/tex] )

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 = [tex]\frac{6}{8}[/tex]

or, x = [tex]\frac{3}{4}[/tex]

Now, Put the value of x in eq B

y = 5 x - 4

Or, y = 5 ×  [tex]\frac{3}{4}[/tex] - 4

or, y =   [tex]\frac{15-16}{4}[/tex]

∴   y = [tex]\frac{-1}{4}[/tex]

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

( x , y ) = (  [tex]\frac{3}{4}[/tex] , [tex]\frac{-1}{4}[/tex] ) Answer
