2x+3y=12 how do i solve for x and y

2x + 3y = 12
2x - 2x + 3y = 12 - 2x
3y = 12 - 2x
 3          3
  y = 4 - 2/3x
2x + 3(4 - 2/3x) = 12
2x + 12 - 2x = 12
2x - 2x + 12 = 12
0x + 12 = 12
       -12   -12
        0x = 0
         0     0
         x = 0
2(0) + 3y = 12
0 + 3y = 12
-0          -0 
      3y = 12
       3      3
        y = 4
  (x, y) = (0, 4)

Od. 130 degrees because if you add them together you get the 130

Ithink you're supposed to multiply 12.50 which is how much he makes per hour and then multiply it by each number then add whats left togrther and there's your answer
