Two ways to see this: 6y=8-9+6y 6y=6y-1 No answer here 6y= 8-(9+6y) 6y+(9+6y)=8 12y+9=8 12y=-1 y= -(1/12) or -0.08333...
3x-6y=9 -3x -3x -6y=9-3x __ ____ -6 -6 y=9-3x ____ -6
6y-3x-9(1-1)=6y-3x-9(0)=6y-3x-0=6y-3xOnly like terms can be simplified. A like term has the same variables, X and Y are different variables. 6y-3x cannot be simplified because they are not like terms.
I think this is what you're asking for.3x=9 can be moved to be x=9/3For a slope/intercept example:3x-6y=-1 Subtract the 3x-6y=-3x-1 Divide the negative 6 on yy=1/2x+1/6 And there, (y=1/2x+1/6) is equal to (3x-6y=-1)
7y-8 = 6y+1 7y-6y = 1+8 y = 9

2x-6y = 9 Rearranging: 6y = 2x - 9 Divide through by 6: y = (1/3)x - 3/2
y/5 = y/6+9 Multiply all terms by 30 to eliminate the fractions 6y = 5y+ 270 Subtract 5y from both sides 6y-5y = 270 y = 270

7y-8 = 6y+1 7y-6y = 1+8 y = 9
8/84 * 6y/84 = 3y/441
-9x+6y = 54 6y = 9x+54 y = 1.5x+9 slope = 1.5
-6y - 9 = 5y + 24Add 6y to each side of the equation:-9 = 11y + 24Subtract 24 from each side:-33 = 11yDivide each side by 11:-3 = y
