Solving for One Variable in Terms of Another Variable
Solve the equation for b.A = bh Which variable am I solving for? h h Divide by h on both sides. A = b Solved for b. h
Solve the equation for h.A = bh Which variable am I solving for? b b Divide by b on both sides. A = h Solved for h. b
Solve the equation for h.V = lwh Which variable am I solving for? lw lw Divide by lw on both sides. V = h Solved for h. lw
Solve the equation for w.V = lwh Which variable am I solving for? lh lh Divide by lh on both sides. V = w Solved for w. lh
Solve the equation for .A = r Which variable am I solving for? r r Divide by r2 on both sides. A = Solved for . r2
Solve the equation for w.P = 2l + 2w Which variable am I solving for? -2l -2l Subtract 2l from both sides. P – 2l = 2w Can’t combine P and -2l Divide both sides by 2. P – 2l = w Solved for w
Solve the equation for h.A = bh Which variable am I solving for? b b Divide by b on both sides. A = h Multiply both sides by 2. b (2) A = h(2) Multiply both sides by b 2A = h Solved for h b
Solve the equation for .V = r2h Which variable am I solving for? r2h r2h Divide by r2h on both sides. V = Solved for . r2h
Solve the equation for z.x + y + z = P Which variable am I solving for? -x -y x -y Subtract x and y from both sides. z = P – x – y Can’t combine P, -x and -y z = P – x – y Solved for z.
Solve the equation for n. - l= m Which variable am I solving for? +l +l Add l to both sides. = m + l Can’t combine m and l (k) = k(m + l) Multiply both sides by k. n = km + kl Solved for n.
Solve the equation for y in terms of x.5x + 6y = Which variable am I solving for? -5x x Subtract 5x from both sides. 6y = -5x Can’t combine -5x and 24 Divide by 6. y = -x Solved for y.
