​

Answer 1

$\color{violet} \boxed{ \colorbox{black}{ \sf{answer}}}$

$y = 3 + 4x \\ = > y = 3 + 4 \times \frac{ - 2}{21} \\ = > y = 3 + \frac{ - 8}{21} \\ = > y = \frac{63 - 8}{ 21} \\ = > y = \frac{55}{21}$

hope it helps.. :)

Answer 2

Answer:

55/21

Step-by-step explanation:

X=-2/21

y=3+4X

First substitute the value of X in y

that means

y=3+4×(-2/21)

=3-(8/21)

=(3×21 - 8)/21

=(63-8)/21

= 55/21

=2.61
