Question

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

Answer 1

Answer:

The value of x and y for the given expression is

( x , y ) = (  $\frac{3}{4}$ , $\frac{-1}{4}$ )

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 = $\frac{6}{8}$

or, x = $\frac{3}{4}$

Now, Put the value of x in eq B

y = 5 x - 4

Or, y = 5 ×  $\frac{3}{4}$ - 4

or, y =   $\frac{15-16}{4}$

∴   y = $\frac{-1}{4}$

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

( x , y ) = (  $\frac{3}{4}$ , $\frac{-1}{4}$ ) Answer
