1.3x + 0.5 minus 5 = 1.1x + 2.5

1.3x + 0.5 minus 5 = 1.1x + 2.5


1.3x+0.5-5=1.1x+2.5
1.3x-1.1x=2.5-0.5+5
0.2x=7
x=35



5.5x-3x = 1.75 how to calculate x?


5.5x-3x=1.75
(5.5-3)x=1.75
2.5x=1.75
x=1.75/2.5
x=0.7



Known: x ^ 2 / (x ^ 4 + x ^ 2 + 1) = 1 / 4, calculate (5x ^ 4-3x ^ 2 + 5) / 3x ^ 2


x^2 / (x^4+x^2+1)=1/4
x^4+x^2+1=4x^2
x^4+1=3x^2
therefore
(5x^4-3x^2+5) / 3x^2
=[5(x^4+1)-3x^2]/3x^2
=(5*3x^2-3x^2)/3x^2
=12x^2/3x^2
=4



3x + 5 = 2 + 5x, how to calculate?


3x+5=2+5x
Transfer: 3x-5x = 2-5
Get: - 2x = - 3
x=1.5
