Answer:
the solution to the equation √(7x + 6) - 9 = -4 is x = 19/7.
Explanation:
you add 9 to both sides of the equation to isolate the square root term:
√(7x + 6) = -4 + 9
√(7x + 6) = 5
then square both sides of the equation to eliminate the square root:
(√(7x + 6))^2 = 5^2
7x + 6 = 25
subtract 6 from both sides to isolate the variable:
7x = 25 - 6
7x = 19
and divide both sides by 7 to solve for x:
x = 19/7
