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
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
5y + (4 - 2y) = 9 5y + 4 - 2y = 9 3y + 4 = 9 3y = 5 y = 5/3
