Explicație pas cu pas:
[tex]\bf 22-5\cdot(38-4\cdot g)=12[/tex]
[tex]\bf 22=12+5\cdot(38-4\cdot g)[/tex]
[tex]\bf 22-12=5\cdot(38-4\cdot g)[/tex]
[tex]\bf 10=5\cdot(38-4\cdot g)[/tex]
[tex]\bf 10:5=38-4\cdot g[/tex]
[tex]\bf 2=38-4\cdot g[/tex]
[tex]\bf 2+4\cdot g=38[/tex]
[tex]\bf 4\cdot g=38-2[/tex]
[tex]\bf 4\cdot g=36[/tex]
[tex]\bf g=36:4[/tex]
