2(x+2)+3x=2(x+1)+1      simplify

2x + 4 + 3x  = 2x + 2 + 1

5x + 4  = 2x + 3       subtract 2x, 4 from both sides

3x  = -1      divide both sides by 3

x = -1/3

OK....if you'll let me live....I'll tell you......  →   "2 pi "

This is the graph of  y =  l x l   shifted to the right by 3 units

Here's the graph of both........https://www.desmos.com/calculator/stctphckrn

"Is" means "='       "Of"  means "multiply"     .....and we have....

12 = .30N     where N is the number we're looking for  ... divide both sides by .30.....

12/.30 = N =  40

D/R = T   ...so...

[5,878,000,000,000 Miles  *  25,000]  / 800,000,000,000,000MPH  = about  183.69 hours.....  [a little more than a week.....!!!]  

We have similar rectangles, here  and the ratio of the sides are the same...so......

Long side of the larger rectangle / short side of the larger rectangle =

Long side of the smaller rectangle / short side of the smaller rectangle

Mathematically, we have......

12/9 = 4/x      cross-multiply

12x = 36    divide both sides by 12

x= 3 inches

Divide 120 by 3......if you get a whole number....it's a factor.....

39/13 = 3 yds per play

-6/3 = -2 yards per play

3 - (-2)  = 5 yds  difference in their averages

When one side of a linear equation in one variable is exactly like the other, we have infinite solutions for  that variable........This is known as an "identity"

2x+3x+3+4x+10+x  =

10x + 13
