Subtract 2 from both sides

-2u = -7u + 17 - 2

Simplify -7u + 17 - 2 to -7u + 15

-2u = -7u + 15

Add 7u to both sides

-2u + 7u = 15

Simplify -2u + 7u to 5u

5u = 15

Divide both sides by 5

u = 15/5

Simplify 15/5 to 3

u = 3

Use the elimination to solve this equation. 2x+3y=55 9x+4y=105

X=5 y=15 (5,15).
This is how you do it:
-4(2x+3y=55): -8x-12y=-220
3(9x+4y=105):27x+12y=315

You add the two new equations together, canceling out the y values, and get the x value. Then, you go back and plug in the x value in the original equation to get the y value.
