Linear Equation

Easy

In the following system of linear equations $7x - 15y = 2$ and $x + 2y = 3$ , the value of x and y is:

$x = 49/29$ and $y = 19/29$

$x = 36/21$ and $y = 11/17$

$x = 32/25$ and $y = 14/23$

$x = 17/15$ and $y = 17/25$

✅ Correct Option: 1

From the second equation, $x = 3 - 2y$ .

Substituting: $7(3-2y) - 15y = 2 \Rightarrow 21 - 29y = 2 \Rightarrow y = 19/29$ .

Then $x = 3 - 38/29 = 49/29$ .
