Answer: -78 / 35
Step-by-step explanation:
<u>Given</u>
2/5 + 3/7 + (-6/5) + (-13/7)
<u>Combine terms that have the same denominator</u>
= 2/5 + (-6/5) + 3/7 + (-13/7)
= -4/5 - 10/7
<u>Convert denominator by Least Common Multiple (LCM)</u>
= (-4 × 7) / (5 × 7) - (10 × 5) / (7 × 5)
= -28/35 - 50/35
= -78 / 35

Note: √(x+5) = 4 ;
Square each side:
[√(x+5)] ² = 4² ;
x + 5 = 16 ;
Subtract "5" from each side of the equation;
x + 5 - 5 = 16 - 5 ;
to get: x = 11 ;
So, yes; there is a solution.
