Can someone please help me with 5 and 6(Best answer = Brainliest)

5.
First plug the value of x into the equation
$2(-2y-12)+y=9$
then solve for y
$2(-2y)+2(-12)+y=9 \\ -4y+(-24)+y=9 \\ -4y-24+y=9 \\ -3y-24=9 \\ -3y=33 \\ \frac{-3y}{-3}= \frac{33}{-3} \\ y = -11$

6. Do the same steps
$5(-y-1)+y=-13 \\ 5(-y)+5(-1)+y=13 \\ -5y+(-5)+y=13 \\ -5y-5+y=13 \\ -4y-5=13 \\ -4y=18 \\ \frac{-4y}{-4}= \frac{18}{-4} \\ y=-4.5$

The equation x+5=27 is solved below. When we describe the first step we say that we "Subtract 5 from both sides." We do not say

Answer:

If you were to move five to the other side, the equation would have a completely different outcome. Instead of x + 5 = 27 it would be x = 27 + 5. Then the answer would be x=32 rather than x=22. You need to do the inverse of the original equation to get the correct solution. (AKA: balancing the equation)

I hope this helps :))
