Xy - 5 = k (move the known term to the right with changed sign) xy = k + 5 Now we have x multiplied for y...to delete the y, divide both terms for y. xy/y = (k+5)/y x = (k+5)/y 3y + 5x = 7 Move 3y to the right with changed sign (this to make x the variable for which we solve the equation) 5x = 7 - 3y Divide every term for 5 5x/5 = 7/5 - 3y/5 x = 7/5 - 3y/5 m/n = p-6 Multiply both terms for n, since we should delete the fraction m/n m = pn-6n Factor... m = n(p-6) to find n, move m to the right with changed sign. Divide both for p-6 m/p-6 = n n = m/p-6 F = 9c/5 + 32 9c/5 + 32 = F Move 9c/5 to the left (don't change sign) to make it the default variable. And move all the rest to the right but changing sign. 9c/5 = f - 32 To delete the fraction, multiply every term for 5 9c = 5(f) + 32(5) 9c = 5f - 160 Divide both for 9 c = 5f/9 - 160/9
