Answer 1

x = 45 / 8

Explanation:

8 x - 3 y = 36

8 x - 3 × 3 = 36 ( given :- y = 3 )

8 x - 9 = 36

add 9 to both side

8 x - 9 + 9 = 36 + 9

8 x = 45

Divide each side by 8

8 x / 8 = 45 / 8

X = 45 / 8

Answer 2

x = 45/8

Explanation:

8x – 3y = 36

Let y=3

8x – 3*3 = 36

8x - 9 = 36

Add 9 to each side

8x -9+9 = 36+9

8x = 45

Divide each side by 8

8x/8 = 45/8

x = 45/8
