-1=-x+2

first you need to get x by itself so you are going to move it to the other side. the way you do this is by subtracting 2.

-3=-x

then you need to divide out a negative 1

x=3

Step-by-step explanation:

(6 y^4+ 3 y^2-7) - (12 y^4 - y^2 + 5 )

=6 y^4 +3 y ^2 - 7 - 12 y^4 + y^2 - 5

=6 y ^4 - 12 y ^4 +3 y ^2 + y ^2 - 7 -5

= -6 y ^4 + 4 y ^2- 12
