g (x) = -3x+5
-3x= 5
x= -5/3
3x + 9 = 42 3x = 33 x = 11
23
x=7
-3x + 5 = 20 -3x = 15 x = -5
-15x=-5*3x+2 -15x=-15x+2 +15x +15x ----------------- 0=2
3x + 9 = 42 3x = 33 x = 11
3
x = -8
23
x=7
x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.
3x + 5 = 20 Subtract '5' from both sides 3x = 15 Divide both sides by '3' x = 5 The answer!!!!!
-3x + 5 = 20 -3x = 15 x = -5
-15x=-5*3x+2 -15x=-15x+2 +15x +15x ----------------- 0=2
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
x = 6
x = -8
