Find the roots
x=-\frac{1}{7}
Alternative Form
x=-0.\dot{1}4285\dot{7}
Evaluate
3\left(7x+1\right)
To find the roots of the expression,set the expression equal to 0
3\left(7x+1\right)=0
Rewrite the expression
7x+1=0
Move the constant to the right side
7x=0-1
Removing 0 doesn't change the value,so remove it from the expression
7x=-1
Divide both sides
\frac{7x}{7}=\frac{-1}{7}
Divide the numbers
x=\frac{-1}{7}
Solution
x=-\frac{1}{7}
Alternative Form
x=-0.\dot{1}4285\dot{7}
