Answer:7.3 repeating
Step-by-step explanation:
First, since these are right across from each other, they are equal. So (x+16)=(4x-5)
Then you would subtract the 4x from both sides. Making the equation (-3x+16) = (-5)
Subtract the 16 from both sides making it a -3x=-22
To turn it positive, divide everything by negative 1 making the equation 3x=22
Divide 22 by 3 and you get your answer.
<span>5(-4) + 2y = -20
-20 + 2y = -20
2y = -20 + 20
2y = 0
y = 0</span>
