Question

2x-7y=1,4x+3y=15 Solve

Answer 1

Hey user here is your answer.....

---> To find - x & y

---> Given equation -

◆ 2x-7y=1--------(1)

◆4x+3y=15-------(2)

◆Equation 1×(2)

◆4x-14y=2------(3)

◆Equation 2 - 3

◆17y=13

◆y=13/17

Put in equation (1)

◆2x-7(13/17)=1

◆2x-91/17=1

◆TAKE LCM

◆34x-91/17=1

◆34x=17+91

◆34x=108

◆x=54/17

Hope it helps you☺️

Answer 2

Answer:

The correct answer to this question is $x = -4$

Step-by-step explanation:

Given - $2x - 7y = 1, 4x + 3y = 15$

To Find - Solve the equation -

$2x - 7y = 1$

$= 2x = 1 + 7y$

$x = \frac{1 + 7y}{2}$

Put the value of $x$ in $4x + 3y = 15$

$4(\frac{1 + 7y}{2}) +3y = 15$

$2 + 14y + 3y = 15$

$= 17 y = 13$

$= y = 13/17$

$4x + 3 ( 13/17 ) = 15$

$4x = (-255 + 15)/17$

$4x = -240/17$

$x = -68/17$

$x = -4$
