The answer is 47.
[tex] \sqrt{ x + 3 - 1} = 7[/tex]
Square both sides of the equation to remove the radical sign.
[tex] { \sqrt{x + 3 - 1} }^{2} = {7}^{2} [/tex]
[tex]x + 3 - 1 = 49[/tex]
[tex]x + 2 = 49[/tex]
Transpose 2 the right side to find x. This will change the sign of 2 to negative.
[tex]x = 49 - 2[/tex]
Subtract the numbers and you'll find x.
[tex]x = 47[/tex]
please mark me the brainliest hehe
