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
