Question

4x + 3y = 14
9x - 2y = 14​

Answer 1

Answer:

x = 0, y = 14/3

4x + 3y = 14

4x = (14 - 3y)

x = (14 - 3y)/4

Substitute this into the second equation.

9(14 - 3y)/4 + 3y = 14

[9(14) - 27y + 12y]/4 = 14

126 - 15y = 14*4 = 56

15y = 126 - 56 = 70

y = 70/15 = 14/3

x = (14 - 3(14/3))/4 = (14 - 14)4

= 0/4 = 0
