Question

4x=1-2y and y=3-x
solve​

Answer 1

$4x = 1 - 2y \\ \\ y = 3 - x \\ \\ 4x = 1 - 2y \\ \\ 4x = 1 - 2(3 - x) \\ \\ 4x = 1 - 6 + 2x \\ \\ 2x = - 5 \\ \\ x = \frac{ - 5}{2} \\ \\ y = 3 - x \\ \\ y = 3 + \frac{5}{2} \\ \\ y = \frac{11}{2}$

Answer 2

Step-by-step explanation:

4x = 1 - 2y

transportation

4x + 2y = 1

6xy = 1

= 6xy\ 1

y = 3- x

transportation

y + x = 3

yx = 3

= yx / 3
