Question

Y - 3 = 2(x+1)

Complete the missing value in the solution to the equation

(-1, )

Answer 1

y=3

Explanation:

You can plug in -1 as x.

There are 2 ways to do this

First

y-3=2x+2

y-3=2(-1)+2

y-3=-2+2

y-3=0

Add 3 on each sides

y=3

Second

y-3=2(-1+1)

y-3=2(0)

y-3=0

Add 3 on both sides

y=3
