-2x+15y+z=44
4x+3y+3z=18
-3x+6y-z=8

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet
