y= -9
No it doesn't. If you look at the problem: -91 = 9 + -18 and solve -91 = -9 Those two are not the same thing, therefore the answer is "No solution" or "No real answer".
20+18+13+9=60
8 + 1 = 9 5 + 4 = 9 9 + 9 = 18 ( 8 + 1 + 5 + 4 = 18) The answer is 18.
9 plus 11 (20) plus 15 (35) plus 18 is equal to 53
3x2 + 33x + 54 =3(x2 + 11x + 18) = 3(x + 9)(x + 2)
y= -9
No it doesn't. If you look at the problem: -91 = 9 + -18 and solve -91 = -9 Those two are not the same thing, therefore the answer is "No solution" or "No real answer".
18 is a solution to the equation 4 plus 7 times a number where the result is 9 times that number.
-18
20+18+13+9=60
x2 + 11x + 18 (x + 9)(x + 2) CHECK: x2 + 9x + 2x + 18 x2 + 11x + 18 SET EACH EQUAL TO ZERO: x + 9 = 0 x = -9 x + 2 = 0 x = -2 NOW YOU ARE DONE: Solution set: {-9, -2}
18 + 9 = 27
8 + 1 = 9 5 + 4 = 9 9 + 9 = 18 ( 8 + 1 + 5 + 4 = 18) The answer is 18.
9 plus 11 (20) plus 15 (35) plus 18 is equal to 53
18
18. 9 x 0 = 0 S0, 9 + 0 + 9 = 18
