<h3>System of Linear Equations</h3>System of linear equations is the given term math for two or more equations with the same variables. The solution of these equations represents the point at which the lines intersect.
- STEP 1 - Convert the text of problem in system of equations
2a+3n=67
3a+2n=78
where: a= adultos and n =niños
- STEP 2 - Find the variables a and n.
Thus, a=20 and n=9.

Then
The coordinates of point P are (-3 , -6)
Step-by-step explanation:
If point (x , y) partitions line AB where A = and B =
at a ratio from A then:
1.
2.
∵ P partitions AB in the ratio 3 : 4
∴ = 3 : 4
∵ A = (-9 , -9) and B = (5 , -2)
- Substitute the coordinates of points A and B in the rules above
∵
∴
∴
∴ x = -3
The x-coordinate of P is -3
∵
∴
∴
∴ y = -6
The y-coordinate of P is -6
The coordinates of point P are (-3 , -6)
