Question

Solve the equation : v3x-5 = 4
v stands for sqrt

A. 7
B. 3
C. 1/3
D. 49

Answer 1

\[\sqrt{3x-5} = 4\]

Answer 2

\[\Large \sqrt{3x-5} = 4\]


\[\Large \left(\sqrt{3x-5}\right)^2 = 4^2\]


\[\Large 3x-5 = 16\]


\[\Large 3x-5+5 = 16+5\]


\[\Large 3x = 21\]


\[\Large \frac{3x}{3} = \frac{21}{3}\]


\[\Large x = 7\]
