5-29.
Solve each of the following equations for the indicated variable.
for Remember the strategies for solving algebraically.
To undo multiplication by 3, divide each term by 3.
for m 2 To undo division by r2, multiply both sides by r2.
To undo multiplication by Gm1 divide both sides by Gm1.
for m (which is the same as dividing by 2), multiply both sides by 2.
To undo multiplication by v2, divide both sides by v2.
(x − 4)2 + (y − 1)2 = 10 for y
To undo addition of (x − 4)2, subtract (x − 4)2 from both sides.
To undo squaring, take the square root of both sides. (Remember ±.)
To undo subtracting 1, add 1 to both sides. Remember to put it outside the radical sign.
