4x=2y-10

[step 1] -2y -2y

-2y+4x=-10

[step 2] -4x -4x

-2y=-4x-10

[step 3] divide both sides by -2

y=2x+5 Â«answer!!

With first equation get x alone on one side.

x = .5y - 2.5

Substitute that value for x in the second equation and solve for y. Put that y value into the first equation to find value of x. To check, put both values into the second equation.

I hope this helps a little more. Thanks for asking.
