Answer:

x = -1,5

Step-by-step explanation:

2x² - 8x - 10

2x² - 10x + 2x - 10

2x(x - 5) + 2(x - 5)

(x - 5)(2x + 2)

x = 5 x = -2/2

Answer:

y = − 1

Hope this helps!

Step-by-step explanation:

Alright so this is our equation:

y − 3   =   2 ( x − 1 )

We will substitute:

x = − 1

So now our equation looks like this:

y − 3   =   2 ( −1 − 1 )

Now we will get rid of the parentheses:

y − 3    =   − 2 − 2

Solve the left side:

y − 3   =   − 4

Now add 3 on both sides to find out what y is:

y − 3   =   − 4

  +3         +3

Add:

y = − 1

Yay! We found our answer! Nice job everyone!
