Hey!
To solve x in this equation we must first add five to both sides to get
on its own.
<em>Original Equation :</em>
<em>New Equation {Added 5 to Both Sides} :</em>
Now we must square both sides of the equation.
<em>Old Equation :</em>
<em>New Equation {Changed by Squaring Both Sides} :</em>
And now we must solve the new equation.
Step 1 - Switch sides
Step 2 - Subtract x from both sides
Step 3 - Simplify
Now we need to solve the rest of the equation using the quadratic formula.

Determine the fraction of Wednesday
The summation of fractions on each day must be equal to 1.
So:
Substitute values for Monday and Tuesday
Collect Like Terms
Take LCM
Simplify fraction
A(b+c)=ab+ac
we have
9(72)=9*?+9*2
c=2
sub, but it must be equal to minus 2 from 72
7(70+2)=9*70+9*2
the question mark is 70
and the restult of the equation is 648
?=70
