Solve the equation: 10y - 3 = -10 + 6y?
373486
10y - 3 = -10 + 6y\n    + 3 =  +3 <-- subtract 3 from both sides  \n-------------------\n10y = -7 + 6y\n-6y =    - 6y <-- subtract 6y from both sides\n---------------\n4y = -7\n--   --\n4  =  4 <-- divide both sides by 4\n\ny = -7/4

3x+4y=10 and 6x-9y=-4 are both linear equations. However, 5xsquared+2y=6 is not because a linear equation can only contain two variables that must both be in the first degree (i.e. they cannot be squared, cubed, etc).

8y=-23-x\n\n-5x+8y=19\n-5x+(-23-x)=19\n-6x-23=19\n-6x=42\nx=-7\n\n-7+8y=-23\n8y=-16\ny=-2\n\n\nThe solution is (-7,-2).  I've checked it, so it works.  However, it is a good idea to always check the solutions.  Since you end up using only one equation to find the second variable, make sure the pair also works in the second equation.\n\nHope this helps!

slope of  6x – 3y=10 is: 6/3=2\nso slope of perpendicular line is: -1/2\nand the equation is:\ny+6 = -1/2 ( x -2) !
