Question

Find the missing coefficient in the equation -x+By=10; (-2,-2)

Answer 1

To find the missing coefficient in the equation -x + By = 10, substitute the given point (-2, -2) into the equation and solve for B. The missing coefficient is -4.

Step-by-step explanation:

To find the missing coefficient in the equation -x + By = 10, we can substitute the given point (-2, -2) into the equation and solve for B.

Using the coordinates of the point, we have:

-(-2) + B(-2) = 10

2 - 2B = 10

Subtracting 2 from both sides, we have:

-2B = 8

Dividing both sides by -2, we get:

B = -4

Therefore, the missing coefficient in the equation is -4.
