(7y + 4)/(y + 2) = -4/3
Cross-multiply:
3(7y + 4) = -4 (y + 2)
Distribute 3 and -4:
21y + 12 = -4y - 8
Add 4y to both sides:
25y + 12 = -8
Subtract 12 from both sides:
25y = - 20
Divide both sides by 25:
y = -20/25
Simplify:
y = -4/5
Answer: y = -4/5

To check, insert y = -4/5 back into the equation:
(7y + 4)/(y + 2) = -4/3
LHS =: (7(-4/5) + 4 ) / ( -4/5 + 2)
LHS = (-28/5 + 4) / (-4/5 + 2)
LHS = (-8/5) / (6/5)
LHS = -4/3
LHS = RHS (Checked)
