Find the roots
k=\frac{1}{7}
Alternative Form
k=0.\dot{1}4285\dot{7}
Evaluate
\left(3-7k\right)-2
To find the roots of the expression,set the expression equal to 0
\left(3-7k\right)-2=0
Remove the parentheses
3-7k-2=0
Subtract the numbers
1-7k=0
Move the constant to the right-hand side and change its sign
-7k=0-1
Removing 0 doesn't change the value,so remove it from the expression
-7k=-1
Change the signs on both sides of the equation
7k=1
Divide both sides
\frac{7k}{7}=\frac{1}{7}
Solution
k=\frac{1}{7}
Alternative Form
k=0.\dot{1}4285\dot{7}
