x cubed plus 7x squared plus 12x divided by x squared plus 2x - 3
x*y+4*y=14
5.899x^2+4x-1.3=0
$2^{x}$=$4^{(7-2y)}$
$3^{(5x-2y)}$=81
53 divided by 2.56
If (2x+3)/(2x-3)=(2x+5)/(2y-5), prove that x/y = 3/5
2(3d + 7) = 4d + 26
x + |1 + 2x| = – 2
7x + 3y = 20 and –4x – 6y = 11. Find the value of 3x – 3y.
$2^{x}$ = $4^{(7-2y)}$
$3^{(5x-2y)}$ =81
