Q:-solve the linear equation

$2x + 3y = 2$

$4x + 5y = 7$

$\huge\tt\underline\blue{ANSWER }$

------>>>>Here is your answer<<<<--------

$⇨2x + 3y = 2$

$⇨x = \frac{2 - 3y}{2} .....(1)$

Put the value of x in another equation:-

$⇨4x + 5y = 7$

$⇨4( \frac{2 - 3y}{2} ) + 5y = 7$

$⇨ \frac{8 - 12y}{2} + 5y = 7$

$⇨ 8 - 12y + 10y = 70$

$⇨ - 2y = 62$

$⇨y = - 31$

Now put the Y's value in equation 1:-

$x = \frac{2 - 3( - 31)}{2}$

$⇨ \frac{2 + 63}{2} = \frac{65}{2} ✓$

HOPE IT HELPS YOU..

Answer 2

Answer:

2x +3y=2

4x+5y=7

answer is_. -3

Step-by-step explanation:

let's multiply both to equal the terms of X

4*first day.

2* second equation

then you will get as

8x+12y=8

8x+10y=14

then solve it

you will get _2y=. -6

so y=. -3
