Step-by-step explanation:
Y=4x+4
Y-4=4x
X=(Y-4)/4

Answer:
i guess it's the second one, 16x2+9y2, since they are both raised to 2 and they are binomial

Answer:
see below
Step-by-step explanation:
-1/2 * (6x + 10) = 13
Distribute -1/2
–3x – 5 = 13
Add 5 to each side
-3x-5+5 = 13+5
–3x = 18
Divide each side by -3
-3x/-3 = 18/-3
x = -6
