Question

For the equation 3 x - 2 y = 17 find the value of x when y = -1 and find the value of y when x = 3.​

Answer 1

Step-by-step explanation:

when y=-1

$3x - 2( - 1) = 17 \\ 3x + 2 = 17 \\ 3x = 15 \\ x = 5$

when x=3

$3(3) - 2y = 17 \\ 9 - 17 = 2y \\ 2y = - 8 \\ y = - 4$

Answer 2

Answer:

for y = -1

3x-2(-1) =17

3x+2 = 17

3x = 17 -2

3x = 15

x= 5

for x = 3

3*3 -2y =17

9 = 17+ 2y

9 - 17 = 2y

- 8 = 2y

y = - 4
