Assuming that the 2 in "5x2" is a power (5x2), then no, this is not a linear equation. It is a parabolic equation.
5x2=10...take 5 two times..5+5=10

5x2 = 3 then x2 = 3/5 so that x = sqrt(3/5) = ± 0.7746
1) 5x2-55=90 +55 +55 2) 10x=145 /10 /10 x=14.5

No.

5x2 - 136 = 44 5x2 - 136 + 136 = 44 + 136 5x2 = 180 5x2/5 = 180/5 x2 = 36 √x2 = √36 x = ±6
5x2y = 3x - 6y 5x2y + 6y = 3x y(5x2 + 6) = 3x y = (3x)/(5x2 + 6) This is a rational function.
5x2-136 = 24 5x2 = 24+136 5x2 = 160 x2 = 32 x = the square root of 32
5x2 = 3 then x2 = 3/5 so that x = sqrt(3/5) = ± 0.7746
1) 5x2-55=90 +55 +55 2) 10x=145 /10 /10 x=14.5
5x2+500 = 844.45 5x2 = 844.45-500 5x2 = 344.45 x2 = 344.45/5 x2 = 68.89 x = the square root of 68.89 = 8.3 x = 8.3
The discriminant is 385.
for x = -2: x2 = 4, -5x2 = -20; 3x = -6 giving -20 - (-6) = - 20 + 6 = -14.
