Subtract 4y from both sides of the equation. X + 4y = 0 The answer is x = -4y
Divide each term in 20y = - 5x by 20 and simplify, the answer is y = - x/4
Subtract 4y from both sides of the equation so the answer to X+4y =0 by solving the equation for X is X= - 4y
Step-by-step explanation:
From eq(1)
Put in eq(2)
