Question

Find the coordinates of point A by solving the system 3x - 2y = 0, x + 2y = 10

Answer 1

(2.5, 3.75), or using fractions, (5/2, 15/4)

Explanation:

3x - 2y = 0

x + 2y = 10

Add the equations and solve for x.

4x = 10

x = 2.5

Substitute x = 2.5 in the first equation, and solve for y.

3(2.5) - 2y = 0

-2y = -7.5

y = 3.75
