2) x-y=11
0,5x-0,2y=4
x=11+y
0,5x-0,2y=4
0,5*(11+y)-0,2y=4
5,5+0,5y-0,2y=4
0,5y-0,2y=4 - 5,5
0,3y=-1,5
y= -1,5/0,3
y= 5
x=11+y
x=11+5
x=16
Obs.: Não sei se este está certo, mas eu fiz.

b) 4x=2+y
3x+2y=7
y=4x-2
3x+2y=7
3x+2(4x-2)=7
3x+8x-4=7
11x=7+4
11x=11
x=11/11 x=1
Valor de y:
y=4x-2
y=4*1-2
y=4-2
y=2

4) 3x+2y=7,20
2x+y=4,40
y=4,40-2x
3x+2y=7,20
3x+2*(4,40-2x)=7,20
3x+8,80-4x=7,20
3x-4x=7,20-8,80
-x=-1,60 *(-1)
x=1,60
Encontrando o valor de y:
y=4,40-2x
y=4,40-2*1,60
y=4,40-3,20
y=1,20
