Equation: x+3=3+x (notice the equal sign: equal; equation)Expression: x+3 (notice no equal sign)
You would set the equation equal to 0 and then solve for x. You may get one or several answers for x, x being the number(s) that make the equation equal 0.
Since there is no x in the equation, it can equal anything at all!
x=0
In that case, x must be equal to zero. (0)
The equation ( x + 5 = 11 ) always equals 11 when ( x ) is equal to 6. Additionally, any equation of the form ( 11 = 11 ) or ( 2x + 3 = 11 ) (when ( x = 4 )) will also equal 11. Essentially, any equation that simplifies to 11 or is set equal to 11 will always equal 11.
At the x-intercept on the graph of the equation, y=0. Take the equation, set 'y' equal to zero, and solve the equation for 'x'. The number you get is the x-intercept.
