A) 3x + 2.5y= 27
B) 5x – 2.5y = 5
Adding A and B we get
8x = 32
x = 4
A) 3*4 + 2.5y= 27
A) 12 + 2.5y= 27
A) 2.5y= 15
y = 6

2 x(3 + 2 x x ) = 54

2(3 + 2x)
6+4x=54

4x = 54-6
4x = 48
4x/4 = 48/4
x = 12

Kinetic energy formula is
K.E = $\frac{1}{2}$ mv²

m = 0.5 kg
v = 3 m/s

Plug in the given.

K.E = $\frac{1}{2}$ × (0.5) × (3)²
= 2.25 J
