V = LWH Rewrite and solve for W LH L H W = V LH
-P A = P + Prt Rewrite and solve for r -P A – P = Prt P t Pt r = A – P Pt
A = ½bh Rewrite and solve for h A =²⁄₁∙ ½bh ²⁄₁∙ 2A =bh b b h = 2A b
A = ½(b₁ + b₂)h Rewrite and solve for b₁ • A =²⁄₁∙ ½(b₁ + b₂)h ²⁄₁∙ • 2A = (b₁ + b₂)h h h - b₂ 2A = b₁ + b₂ h - b₂ b₁ = 2A h - b₂
X + 2Y = 7 Solve for x -2Y -2Y X = 7 – 2Y
X + 2Y = 7 Solve for Y - X -X 2Y = 7 – X 2 2 Y = 7 – X 2
-2X + 3Y = 6 Solve for X - 3Y -3Y -2X = 6 – 3Y -2 -2 X = 6 – 3Y -2
-2X + 3Y = 6 Solve for Y + 2X +2X 3Y = 6 + 2X 3 3 Y = 6 + 2X 3
