Question

solve for x & y: 5x+2y=14 6x+3y=24. explain it. thanks. :D

Answer 1

5x + 2y = 14

6x +3y = 24 -----> it will be ---> y = (24-6x)3 or y = 8 -2x

so subtitute it to the first equation

5x + 2(8-2x) = 14

5x + 16 - 4x = 14 ---> add all x and transpose 16 to other side

x = 14 - 16

x = -2 ----. substitute it to the 2nd equation

6(-2) + 3y = 24

-12 + 3y =24

3y = 36

y = 12


x = -2 and y = 12
