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
