What does x equal when 8x plus 7 equals 2x plus 49?
Remember in algebra any operation you do to one side of the equaution and also to the other side does not affect the eqaution 8x + 7 = 2x + 49 subtract 2x from both sides 6x + 7 = 49 subtract 7 from both sides 6x = 42 divide both sides by 6 x = 7

Find the value of c for which the roots of 2x2-21x c0?
2x^2 - 21x + c = 0 x^2 - 21x/2 + c/2 = 0 (x + a)(x + 2a)= x^2 - 21x/2 + c/2 x^2 + 3a + 2a^2 3a = -21/2 ------> a = -7/2 2a^2 = c/2 ---> 49/2 = c/2 ---> c = 49
