well we can't simiply solve that problem. we must no what y= to solve this. So u can only simpify ok combine like terms. 2y plus 9y is 11y. your answer is 11y+9
5y = 2y+9 5y-2y = 9 3y = 9 y = 3
x = -1.2, y = -3
If: -4x+2y = 9 Then: 2y = 4x+9 Divide all terms by 2: y = 2x+4.5 which is now in slope intercept form
By elimination: x = 3 and y = 0
There are two expressions in the question but no equation - so nothing to solve.
2y + 3 = 3y + 9 2y - 3y = 9 - 3 or -y = 6 so y = -6
x = y+3 x+2y = 9 => x = 9-2y y+3 = 9-2y 2y+y = 9-3 3y = 6 y = 2 and x = 5

5y = 2y+9 5y-2y = 9 3y = 9 y = 3
Solving for y: 5y = 9 + 2y 5y - 2y = 9 3y = 9 y = 9/3 = 3
x = -1.2, y = -3
If: -4x+2y = 9 Then: 2y = 4x+9 Divide all terms by 2: y = 2x+4.5 which is now in slope intercept form
Oh, dude, it's like super easy. So, you can factor out the greatest common factor, which in this case is 3. So, you get 3(2y + 3). And that's it, you're done! Math problem solved, like, no big deal.
By elimination: x = 3 and y = 0
(2y + 3)(4y^2 - 6y + 9)
Add 2y - 4 to each side; 5y - 13 = 0 so y = 2.6
