Answer :
Answer Problem 1: 3*(y+4)
Show Work:
1) y = (1/3)*x-4 // - (1/3)*x-4
2) y-((1/3)*x)+4 = 0
3) (-1/3)*x+y+4 = 0
4) y-1/3*x+4 = 0 // - y+4
5) -1/3*x = -(y+4) // : -1/3
6) x = (-(y+4))/(-1/3)
7) x = 3*(y+4)
8) x = 3*(y+4)
Answer Problem 2: Y=-7/12
Show Work:
Step 1: Flip the equation.
7/3 x+4=y
Step 2: Add -4 to both sides.
7/3x+4+−4=y+−4
7/3x=y−4
Step 3: Divide both sides by 7/3.
