y+2=1\left(x-4\right)
The opposite of -2 is 2.
y+2=x-4
Use the distributive property to multiply 1 by x-4.
x-4=y+2
Swap sides so that all variable terms are on the left hand side.
x=y+2+4
Add 4 to both sides.
x=y+6
Add 2 and 4 to get 6.
y+2=1\left(x-4\right)
The opposite of -2 is 2.
y+2=x-4
Use the distributive property to multiply 1 by x-4.
y=x-4-2
Subtract 2 from both sides.
y=x-6
Subtract 2 from -4 to get -6.
