There are an infinite number of them.
They are:
x = any number
y = 9.5
(5,3)
(0,7)
It equals 285
x+y=15, or y=15-x4x+3y=38Substitute y in 2nd equation with 15-x:4x+45-3x=38x=-7y=15-(-7)=22(-7,22)
-9
(5,3)
(0,7)
15
It equals 285
x+y=15, or y=15-x4x+3y=38Substitute y in 2nd equation with 15-x:4x+45-3x=38x=-7y=15-(-7)=22(-7,22)
15 + 15 + 15 => 30 + 15 = 45 or asnother way ; by colu,m 15 15 15 + 45 ====
15
30
-9
15 plus -3 equals 12 12 divided by -6 equals -2
'x' = WHAT x + 15 = 23 Subtract '15' from both sides x = 23 - 15 x = 8 The answer!!!!!
-15 plus 20 is 5.
