Y-3=2(x+1)
Complete the missing value in the solution to the equation.
(-1, )

Y = 3

Step-by-step explanation:

First add 3 to both sides to get rid of the (-3) on the left.

y - 3 + 3 = 2( x + 1 ) + 3 which is y = 2( x + 1 ) + 3

Now multiply the number associated with the parentheses:

y = 2x +2 + 3  then you can add the two numbers without variables.

y = 2x + 5

So now if X = -1 and you put it into that equation, you get:

y = 2(-1) + 5  which is  y = -2 + 5

and finally y = 3

You could also do this another way.  Plug the value of x into the original equal on the right side so you have this:

y - 3 = 2( -1 + 1 )   you see that -1 + 1 is equal to 0 so 2 times 0 is 0

you are left with  y - 3 = 0

if you add 3 to both sides you get y - 3 + 3 = 0 + 3 which turns into

y = 3
