-3x + 5 = 20 -3x = 15 x = -5
68
y=16 x= -4
3x + 5 = 20 Subtract '5' from both sides 3x = 15 Divide both sides by '3' x = 5 The answer!!!!!
3x+5=20 x=5 since 5x3+5=20
23
x=7
x = -8
3
x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
x = 6
