x = 3
Step-by-step explanation:
2x - y = 4
y = -2x + 8
-y = -2x + 4
y = -2x + 8
0 = -4x + 12
-4x = -12
x = 3
Answer :
<em>( 6 y^4 + 3 y^2 -7) - (12 y^4 - y^2 + 5)</em>
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
Hope this helps!
