If your solving for for y, then simplify both sides of the equation, then isolating the variable.
y = 20

Y equals 20 because what is 100 - 20 is 80 so you have a year and then you at 10 on today and got 90 so y equals 20

Rearrange 8x +2y+11=0 into y=mx+b

Anna007 [38]

Answer:

y = 4x + 5.5

Step-by-step explanation:

We put 2y in the y spot, obviously

2y = mx + b

Then we put 8x in the x spot

2y = 8x + b

Then we put 11 in the b spot

2y = 8x + 11

Then, to simplify, we divided by equation by two (it still gives the same results)

y = 4x + 5.5
