Answer:

1 = brother's age now.

4 = brothers age in 3 years.

7 = girls age now.

10 = girls age in 3 years.

Step-by-step explanation:

You want to get x by itself first.

(x + 6) + 3 = 2(x + 3) + 2

x +9 = 2x + 8

-x + 9 = 8

-x = -1

x = 1

This is her brothers age when she is 6 years older than him.

Now you will take the 1 and put it in the x +3 = brother's age in 3 years.

The brother will be 4 in 3 years.

The girl will be 7 when her brother is born.

Then you will take the 1 and put it into (x + 6) +3 = 10.

The girl will be 10 in 3 years.

1 = brother's age now.

4 = brothers age in 3 years.

7 = girls age now.

10 = girls age in 3 years.

Answer:

y = 2x - 6 or y = 2/1x - 6

Step-by-step explanation:

Remember that the slope-intercept formula is y = mx + b. The "m" is always going to be the slope, and "b" is what the y-intercepts at. The slope could also be a fraction (meaning it rises up 2 and goes to the right 1). If you were to graph it using "2" as the slope, it would be done the same way.

I hope I didnt miss anything and that this helps! :)
