Inequation:
sgrt2sin(pi/2-2x)>1
(2x^2-5x+2)^0,5/(2x^2+6x)<=0
a*x>3
abs(2*x*x)<1
Identical expressions
(seven / five)*(two *x- four)-(six / five)*x<(four / five)*(thirteen - three *x)
(7 divide by 5) multiply by (2 multiply by x minus 4) minus (6 divide by 5) multiply by x less than (4 divide by 5) multiply by (13 minus 3 multiply by x)
(seven divide by five) multiply by (two multiply by x minus four) minus (six divide by five) multiply by x less than (four divide by five) multiply by (thirteen minus three multiply by x)
(7/5)(2x-4)-(6/5)x<(4/5)(13-3x)
7/52x-4-6/5x<4/513-3x
(7 divide by 5)*(2*x-4)-(6 divide by 5)*x<(4 divide by 5)*(13-3*x)
Similar expressions
(7/5)*(2*x-4)+(6/5)*x<(4/5)*(13-3*x)
(7/5)*(2*x-4)-(6/5)*x<(4/5)*(13+3*x)
(7/5)*(2*x+4)-(6/5)*x<(4/5)*(13-3*x)

(7/5)(2x-4)-(6/5)x<(4/5)(13-3*x) inequation

$$- \frac{6 x}{5} + \frac{7 \left(2 x - 4\right)}{5} < \frac{4 \left(13 - 3 x\right)}{5}$$

-6*x/5 + 7*(2*x - 4)/5 < 4*(13 - 3*x)/5
