A lack of spacing between symbols indicates multiplication. In this case, "4x" is another way of saying "4 times x", or "x + x + x + x".
'x' is an unknown variable. For example, if you were to say:
4x = 8
That's a way of saying "four times a certain value is equal to eight". The solution in this case is that x equals two, as four times two is equal to eight. You can see this by dividing both sides of the equation by four:
4x = 8
4x / 4 = 8 / 4
x = 2
Means x = 3
Yes if you mean: y-4x = 3
-3
Normal rules mean x takes precedent over +, so you get 24 +4x. But if you mean 12(2+4x) then it's 24+48x
2
5
Do you mean 4x-3y = 12 then it is at (3, 0)
