Solve the question : 20p / 3 = 40, p = 6, Solve the equation : -p / 3 = 5, p = -15, Solve the equation : 3p / 4 = 6, p = 8, Solve the equation : 3s = -9, s = -3, Solve the equation : 3s + 12 = 0 , s = -4, Solve the equation : 2q = 6, q = 3, Solve the equation : 2q - 6 = 0, q = 3, Solve the equation : 2q + 6 = 0, q = -3, Solve the equation : 2q + 6 = 12, q = 3, Solve the equation : 12p - 5 = 25, p = 5/2, Solve the equation : 4(m + 3) = 18, m = 3/2, Solve the equation : -2 (x + 3) = 8, x = -7, Set up an Equation for the given statement : Irfan says that he has 7 marbes more than five times the marbles Parmit has. Irfan has 37 marbles. (Take m to be the number of Parmit's marbles)., 5m + 7 = 37, Set up an Equation for the given statement : Laxmi's father is 49 years old. He is 4 years older than three times Laxmi's age. (Take Laxmi's age to be y years). , 3y + 4 = 49, Set up an Equation for the given statement : The teacher tells the class that the highest marks obtained by a student in her class is twice the lowest marks plus 7. The highest score is 87. (Take the lowest score to be l).  , 2l + 7 = 87, Set up an Equation for the given statement : In an isosceles triangle, the vertex angle is twice either base angle. (Let the base angle be b in degrees. Remember that the sum of angles of a triangle is 180 degrees)., 4b = 180 degrees.
