Question

Select Yes or No to indicate whether each value of x is a solution to the given equation.

31=x+1

Answer 1

Yes for:

x = 30

Explanation:

Since 31 = x+1

Simplifying, 1 is deducted from 31 to get 30

This gives the two sides of the equation as 30 = x

Therefore, x = 30

This is a simple equation. It can easily calculate the value of x given the value on the other side of the equation. Therefore, x is a dependent variable in this system of equation. And just like every system of equation, the simple equation problem requires that the two sides of the equation are always kept in balance or equilibrium.
