Question

11x+15y+23=0;7x-2 solve x and y

​

Answer 1

Answer:

$x = 0.2 \\ y = 1.7$

Step-by-step explanation:

Given:-

$11x + 15y + 23 = 0 \\ 7x - 2 = 0$

$7x - 2 = 0 \\ 7x = 2 \\ x = \frac{2}{7} = 0.2$

$11( \frac{2}{7} ) + 15y + 23 = 0 \\ \: = > \frac{22}{7} + 15y + 23 = 0 \\ = > \frac{22}{7 } + 23 + 15y = 0 \\ = > \: \frac{22 + 161}{7} + 15y = 0 \\ = > 15y = - \frac{183}{7} \\ = > y = - \frac{183}{7 \times 15} \\ = > y = - \frac{183}{105} \\ y = 1.7$
