To find the solution for x, you must first isolate the variable. So add 4x to both sides to make all the x's on the same side. The equation should now look like [tex]2x+4x-5=7[/tex], the equation is now [tex]6x-5=7[/tex]. So now add 5 to both sides to completely isolate the x variable. [tex]6x=7+5=12[/tex]. Now you know that 6x=12. So dividing both sides by 6 makes the answer 2. So the value of x is 2
