Question

6x4-5+3X3=
22-2x3x2+6x1=
13x[5-2x(11-9)]=
17-2x(3+5x1-8)=
44-{2x[5-(94x0)]}=
5x{3+[2x(6-1x4)]}=

Answer 1

6x4-5+3x3
24-5+9
19+9
28

22-2x3x2+6x1
22-12+6
10+6
16

13x[5-2x(11-9)]
13x[5-2x.2]
13x[5-4x]
65x-52x²

17-2x(3+5x1-8)
17-2x(3+5-8)
17-2x(8-8)
17-2x.0
17-0
17

44-{2x[5-(94x0)]}
44-{2x[5-0]}
44{2x.5}
44.10x
10x=44
x= 44/10
x = 4,4

5x{3+[2x(6-1x4)]}
5x{3+[2x(6-4)]}
5x{3+[2x.2]}
5x{3+4x}
15x+20x²
