Answer:
x=2
Step-by-step explanation:
Given a linear equation with x as a variable
The equation is
[tex]2x^4+4-12 =20[/tex]
Now add 12 to both the sides
[tex]2x^4 =20+12 = 32[/tex]
Divide by 2
[tex]x^4 = 16[/tex]
Take 4th root both the sides
we get
x =2
So answer is x=2
Verify:
Substitute 2 for x in the equation given and check
Left side = [tex]2(2^4) -12 = 32-12 =20\\= Right side[/tex]
