Solve for j. sqrt 7j = sqrt ( 2j + 10) j = _____

Square both sides: Square both sides of the equation to eliminate the square roots. (sqrt(7j))^2 = (sqrt(2j + 10))^2 7j = 2j + 10Subtract j terms: Subtract 2j from both sides to get all the j terms on one side. 7j - 2j = 2j + 10 - 2j 5j = 10Divide by 5: Divide both sides by 5 to solve for j. 5j / 5 = 10 / 5 j = 2

Q. Solve for

j

\newline

\sqrt{7j} = \sqrt{2j + 10}

\newline

j =

_____

Square both sides: Square both sides of the equation to eliminate the square roots. $\newline$ $(\sqrt{7j})^2 = (\sqrt{2j + 10})^2$ $\newline$ $7j = 2j + 10$
Subtract $j$ terms: Subtract $2j$ from both sides to get all the $j$ terms on one side. $\newline$ $7j - 2j = 2j + 10 - 2j$ $\newline$ $5j = 10$
Divide by $5$ : Divide both sides by $5$ to solve for $j$ . $\frac{5j}{5} = \frac{10}{5}$ $j = 2$
