3x-6y=-8
7y-8 = 6y+1 7y-6y = 1+8 y = 9
Subtracting gives: 10x = 80 so x = 8 and y = 5
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...
yes
-6y+3 = -7y+8 -6y+7y = 8-3 y = 5
3x-6y=-8
7y-8 = 6y+1 7y-6y = 1+8 y = 9
Subtracting gives: 10x = 80 so x = 8 and y = 5
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...
yes
x = -8, y = 10
Solving these simultaneous equations by the elimination method:- x = 1/8 and y = 23/12
5y + 3 = 6y + 8 Subtract 5y from both sides: 3 = y + 8 Subtract 8 from both sides: -5 = y So y = -5
6y-5=8+10y 6y-10y=8+5 -4y=13 y=-3.,25 because: 6*3.25-5=-24,5 and 8+10*3.25=-24,5 true
6y-1+8=32 first add -1+8 then your answer move it to the other side of the equation 6y=25 then divide by 6 to live y alone y=25/6
y=3.25 I believe that is the answer.......I have not math like that in a while.
