12x = 36
x=4 or x=-4
y=(-1) x=(2)
there are two method which you can you use to show this. first X+14=22 by putting 8 in place of X if LHS =RHS, then it is the solution of the euation 8+14 = 22 22=22 hence LHS =RHS
What is the solution set of 2x2 + x = 15
No, it is not.
-8
No because x = 2
x=14
x=4 y=4
x-3x = -8 -2x = -8 x = 4
(x-9)(X+8)
If: x-3 = 8 then x = 11 which has only one solution
y = 0 and x = 8.
x - 8 = 17x = 25 (add 8 to both sides)
x=2
It is a basic solution
