It depends what x is. If you do not know the value of either variable it would be 2x.
X + X + X + X = 4x It is the same as 4 x X = 4x Think numbers . 3 + 3 + 3 + 3 = 12 = 4(3) or 4 x 3 = 12 = 4(3) In mathematics instead of writing a 'string of plusses(+), it is easier to write the number of plusses multiplied to the given number.
You will learn MX+B in algebra. M is the slope, X can be any number, and B is the y-intercept. :)
Looking at this as an algebra equation, x + 82 = 180, all you need to do is isolate x. To do this, subtract 82 from both sides of the equation to get x = 98.
500+200+60 + x = 5267 760 + x = 5267 Subtract '760' from both sides x = 5267 - 760 = 4507 The unknown number is 'x' = 4507.

If: 12 = x+6 Then: x = 6
x = 7
That's an equation where x = 5
The pile of leaves, an 'unknown,' would be the 'x' in 'x+6.'
12 (x is -3)
x+x+1=5 add the x's subtract one from both sides 2x=4 divide by two, x=2.
The equation F X 2X plus 5 equals 0.5. This is a algebra math problem.
