2x + 21 = 97
2x = 76
x = 38
Check it.
5 x 38 + 21- 3 x 38
190 + 21 - 114
211 - 114 = 97
It checks.
x = -5
-5x=3+y x=-1/5y-3/5
yes there is.-5x+1=-10-5x=-11-x=-11/5x=11/5
x=-2, y=2
That equation has no solution. There is no possible number that's equal to 18 more than itself.
you cant
x = -5
(10,13)
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
-5x=3+y x=-1/5y-3/5
yes there is.-5x+1=-10-5x=-11-x=-11/5x=11/5
x=-2, y=2
If: 5x+2y = 9 Then: y = -2.5x+4.5 in slope intercept form
That equation has no solution. There is no possible number that's equal to 18 more than itself.

Both of them are equations!The solution is (x, y) = (2, 1).
