You can
put this solution on YOUR website!
multiply the first equation by 2 to get:
10x + 12y = 10
your 2 equations are now:
10x + 12y = 10
10x + 12y = 10
subtract second equation from first to get:
0 + 0 = 0
since the equation is true, and all variables have canceled out, the 2 equations are identities meaning that they are really the same equation.
if you graphed both these equations, they would show up as being the same line.
take 5x + 6y = 5 and solve for y to get y = -(5/6)x + (5/6)
take 10x + 12y = 10 and solve for y to get y = (10/12)x + (10/12)
simplify the second equation to get y = (5/6)x + (5/6)
same equation will graph as the same line.
the equations are identical.
just to s how you, i will graph the 2 equations of y = (5/6)x + (5/6) and y = (10/12)x + (10/12)
see below:
both equations are identical so the graph of both of these equations looks like the same line.
