you cant
y = -4;
(20 - x)/5
If: 20x+5y = 15 Then: y = -4x+3
(1, -1)
5y = 3y + 12 5y - 3y = (3y - 3y) + 12 2y = 12 y = 6
Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
-x + 5y = 10 5y= 11 y = 11/5
6y + 2 = y + 17 => 5y = 15 => y = 3
y = -6
4x-5y+20 = 0 -5y = -4x-20 y = 4/5x+4 which is now in slope intercept form
