1. Write the distance of the point (2, -3) from X axis and Y axis.
2. Write the coefficient of variable 'x' in the linear equation x(x + 9) = -x(7 - x) + 15
1. Distance from x axis = 3 units towards down
Distance from y axis = 2 units towards right
2. x(x + 9) = -x(7 - x) + 15
→ x² + 9x = -7x + x² + 15
→ 16x = 15
The coefficient of x is 16

1. The distance of point P(2,-3) from x-axis and y-axis
is 3 units and 2 units respectively.
2. x(x +9) = -x (7-x) + 15
=> x²+9x = -7x + x² + 15
=> 9x + 7x = 15
=> 16x = 15
Therefore, the coefficient of x in the linear equation
is 16.
Hope it clears all your doubts.
