Answer: $\frac{\big{3+y}}{\big{y}}=7\ \ \ \Rightarrow\ \ \ D:\ y \neq 0\n\n \frac{\big{3+y}}{\big{y}}\cdot y=7\cdot y\n\n3+y=7y\n\ny-7y=-3\n\n-6y=-3\ /:(-6)\n\ny= (3)/(6) \n\ny= (1)/(2) \ \in\ D$

Answer 2

Answer: $(3 + y)/(y) = 7 \n \n 3 +y = 7y \n \n 1y - 7y = -3 \n \n -6y = -3 \n \n y = (-3)/(-6) = (1)/(2) \n \n y = (1)/(2)$

remember, you can do anything to an equaiton as long as you do it to both sides

try to get the unknown by itself

distributive property
a(b-c)=ab+ac

distribute first
1/3(9x-6)=9/3x-6/3=3x-2

now we have

3x-2=2x+3
minus 2x boh sies
3x-2x-2=2x-2x+3
1x-2=0+3
add 2 both sides
x+2-2=3+3
x+0=5
x=5
