What is the solution to the equation?

UkoKoshka [18]

$\frac{1}{3}x+\frac{1}{3}(2x-15)=3\frac{1}{2}\\\\
\frac{1}{3}x+\frac{1}{3}(2x-15)=\frac{7}{2}\ \ \ |Multiply\ by\ 6\\\\
2x+2(2x-15)=21\\\\
2x+4x-30=21\\\\
6x-30=21\ \ |Add\ 30\\\\
6x=51\ \ \ |Divide\ by\ 6\\\\
\boxed{x=\frac{51}{6}=8\frac{1}{2}}$

What is the value of the y coordinate of any point on the x axis?

Leona [35]

The value of the y coordinate of any point on the x axis is always 0.

<u><em>Explanation</em></u>

Suppose, the co ordinate of any point is $(a,b)$ .

It means, the distance of the point from x-axis is ' $b$ ' and distance from y-axis is ' $a$ '.

Now if the point lies on the x-axis, that means the distance of the point from x-axis will be 0. Thus, the value of ' $b$ ' will be 0.

So, the value of the y coordinate of any point on the x axis is always 0.
