Question
17-22a
Find the roots
a=\frac{17}{22}
Alternative Form
a=0.7\dot{7}\dot{2}
Evaluate
17-22a
To find the roots of the expression,set the expression equal to 0
17-22a=0
Move the constant to the right-hand side and change its sign
-22a=0-17
Removing 0 doesn't change the value,so remove it from the expression
-22a=-17
Change the signs on both sides of the equation
22a=17
Divide both sides
\frac{22a}{22}=\frac{17}{22}
Solution
a=\frac{17}{22}
Alternative Form
a=0.7\dot{7}\dot{2}
