Hi Conny;
6xy=22
y=8
(6x)(8)=22
Subtracting a negative number is the same as adding a positive number...
6x+8=22
Let's subtract 8 from both sides...
8+6x+8=228
6x=14
Let's divide both numbers by 6..
(6x)/6=14/6
x=14/6
x=7/3
Let's check our work...
6xy=22
[(6)(7/3)](8)=22
(42/3)+(8)=22
14+8=22
22=22
