Question

Find the value of b if (-3,4) is a solution of the equation 2x – 9y = b​

Answer 1

Answer:

Given that, (−m,3) is a solution of equation 4x+9y−3=0

Then, (−m,3) lies this equation,

Now,

4x+9y−3=0

⇒4(−m)+9(3)−3=0

⇒−4m+24=0

⇒−4m=−24

⇒m=6

Answer 2

Step-by-step explanation:

2x-9y=b

18xy=-34. b=-34

Xy= 34/18
