X + y = 85
2x + 4y = 218
x = 85 - y
2(85 - y) + 4y = 218 
170 - 2y + 4y = 218 
170 + 2y = 218 
2y = 48 
y = 24 
x = 61

$\frac{y}{2} -(-1.12)=3.12$

Simplify:

$\frac{1}{2} y+1.12=3.12$

Subtract 1.12 on both sides:

$\frac{1}{2} y+1.12-1.12=3.12-1.12$

$\frac{1}{2} y=12$

Multiply both sides by 2:

$2\times(\frac{1}{2} y)(2)\times(2)$

$y=4$
