Find y: -6y - 7 =29 Please give at least somewhat of an explanation because I am so confused and need help to understand.

y = -6

Step-by-step explanation:

-6y + -7 = 29

       +7    +7

      -6y = 36  

       -6      -6

          y = -6

Here's our original equation. We're trying to get y by itself, so we first subtract seven. (What you do to one side, you do to the other). That leaves us with -6y = 36. Next, let's divide both sides by -6. This leaves us with our final equation, y = -6. I really hope this helps!

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
