The square root of the quantity 2 x minus 7 end quantity equals 1.

Answer 1

Make sure when you simplify the equation do it to both sides and the answer is
X = 4

Answer 2

Explanation:

= 7 ( square both sides )

11x + 5 = 7² = 49 ( subtract 5 from both sides )

11x = 44 ( divide both sides by 11 )

x = 4

substitute x = 4 into the left side of the equation and if equal to the right side , then it is the solution.

= = = 7 ← equals right side

then x = 4 is the solution
