Solve for d. sqrt 5d = sqrt ( –4 + 7d) d = _____

Square both sides: Square both sides of the equation to eliminate the square roots. (sqrt(5d))^2 = (sqrt(–4 + 7d))^2 5d = –4 + 7dSubtract 7d: Subtract 7d from both sides to get all the d terms on one side. 5d - 7d = –4 + 7d - 7d -2d = –4Divide by -2: Divide both sides by -2 to solve for d. -2d / -2 = –4 / -2 d = 2

Q. Solve for

d

\newline

\sqrt{5d} = \sqrt{\left(-4 + 7d\right)}

\newline

d =

_____

Square both sides: Square both sides of the equation to eliminate the square roots. $\newline$ $(\sqrt{5d})^2 = (\sqrt{\text{–}4 + 7d})^2$ $\newline$ $5d = \text{–}4 + 7d$
Subtract $7d$ : Subtract $7d$ from both sides to get all the $d$ terms on one side. $\newline$ $5d - 7d = -4 + 7d - 7d$ $\newline$ $-2d = -4$
Divide by $-2$ : Divide both sides by $-2$ to solve for $d$ . $\newline$ $\frac{-2d}{-2} = \frac{-4}{-2}$ $\newline$ $d = 2$
